This is only my theory based upon education, observation and a little research. Qualified Psychiatrists, which I am not, no doubt should weigh in but I hope they will consider this possible disorder before coming to their final pronouncements.
So far the police officers and lawyer who've met and talked with Breivik came away from their interactions with him with the conviction that he is absolutely insane. But they do not understand the significance of the symptomatic behavior he has exhibited.
Breivik actions and personality reminded me of something I came across while memorizing the DSM in school and so I examined current descriptions of the disorder. That disorder is Schizotypal Personality Disorder. Every medical and psychiatric site has a slightly different description of it but it all fits Breivik to a T.
Odd beliefs - An early definition of this from years ago said people with this disorder often seem lucid but will relate things that cannot be true. Someone with this might go to the police and calmly and rationally insist that their neighbor is pointing a death ray at them, or that they have been abducted by a UFO. But in all other respects they seem perfectly mentally competent.
The police officers and lawyer were flummuxed by the sheer oddness of what he was saying to them (I don't know if it was the same as in his "manifesto"). Police all have experience with paranoid schizophrenics so would have realized pretty quickly that his cognition and perceptions were impared if they had been. But they didn't seem to be even though he was saying such odd things.
Extreme eccentricity- we all saw the photos and he spent god knows how long patching together that "manifesto".
Social avoidance- He took a year off to play video games. And have you noticed that there have been no friends comming forward to talk about him?
Odd manner of speech (I think this was described by police but am not sure. I think they did discuss his general extreme oddness aside from his beliefs).
Paranoia (bingo) yet not full blown paranoid schizophrenia with attendant breakdown of congnitive functions. If you have ever had the distinct discomfort of talking to a paranoid schizophrenic they at first seem insistant about something , then you think you are having trouble following what they are saying, then you realize it is in fact a stream of conciousness where one sentance is leading to another with no actual connected narrative. In contrast Breivik was saying extremely odd things but in a coherent way.
Chance of degredation into schizophrenia, that may be what changed him from being a quiet loner into a violent pscyhopath. He may have started on his way to full blown paranoid schizophnrenia yet still have worldly competance.
Chance of violent psychotic attacks. Nothing needs to be said.
Conversly he does not appear to conform to the definition of Narcissism.
Such people require constant POSITIVE reactions and ONLY POSITIVE reactions (hysterionics require any reaction). Breivik did not expect a positive responce for his act.
They brag about themselvs and are envious so constantly PUT EVERYONE else down. Breivik expresses admiration for Al Quida of all things, just the sort of nemisis a narcissist would need to belittle. (caevat: he does put down the EDL people who were doing far more then he ever did).
Such people interact with others in order to manipulate and exploit them. It doesn't seem like Breivik, who didn't appear to actually have any social life whatsoever. Not even people who hate him. Which there would be if he was a narcissist. Though people might yet come forward, the press hasn't appeared to find anyone.
I am not saying he is not responsible for and does not understand the consequences of his actions. I am not saying he is deserving of an insanity plea. There are all sorts of disorders where the person is fully lucid and competant and understands the results of their actions.
Here is a video of a psychiatrist describing Schizotypal Personality Disorder. See if it reminds you of Breivik.
Schizotypal Personality Disorder
You should also find on that page a vid of this psychiatrist describing narcissism.
UPDATE: The Psychiatrists who examined him concluded that he has Paranoid Schizophrenia and was Psychotic during the mass murder. The assessment is was published in english and is fascinating reading. The comments below it also bear reading but are more technical. Psychiatric assessments are not written in stone but these were working experts who had direct access to Anders Breivik so their conclusions should be taken with far less salt than mine.
As far as that highly innacurate assesment that he is a Narcissist that was bandied about by a psychiatrist on the TV news- the assessment does discuss his lack of empathy regarding the victims and their families but at no time say he is Narcissistic. They say that symptoms of his paranoid schizophrenia have to be noticiably absent for a period of time before his underlying personality can even be assessed. So it is far too soon to say he has any personality disorder at all, let alone what it might be.
Schizotypal Personality Disorder is on the Schizophrenia scale so isn't really a personality disorder per se despite it's name - So my assessment that he could have had SPD which turned into Paranoid Schizophrenia is still an acceptable interpretation - though it's possible that it was paranoid schizophrenia without previously being SPD.

They could be perverts or it could be propoganda to discredit them. Or it could be for another reason...
With what we know of the general islamic obsession with "purety" and the erotic associations with innocnece and youth, does make it plausable that an extremely intensified indoctrination in the belief system might cause this sort of perversion. Especially with terrorists because they are fighting to make the world "pure" and expect the "holy" reward of sexual gratification from virgins and pure young boys.
I'm not saying it's the normal relationship with the religion that could cause this. Rather it is the far more intense indoctrination terrorists recieve that might cause this obsession to develop.
HOWEVER-
When doing a search about terrorists and child pornography I VERY QUICKLY found mention of digital Steganography.
Stegonography is hiding information within other information. Like using the first letter of each word in a message to express the true message of a letter. Or using lemon juice to write a message.
Digital Steganography is the concealment of information within computer files such as a document file, email or IMAGE file (also executables). You use software to hide the message in the data file and the reciever uses software to extract that message. The Sept 11 plotters used steganography to communicate with each other. The simplest method to detect modified files is to use software to compare them to known originals.
People have posited that terrorists hide messages inside chld pornography and transfer the images via child pornography sites. There are 4 benifits to this:
1. Pedo sites are clandestine operations already. And if they get busted it's no skin off the terrorists nose as they are just piggy backing on the operation.
2. The scumbags running those sites won't call the police on them even if they do suspect their illegal site is being exploited by terrorists.
3. The shocking content of the images is perfect cover - it is so shocking people won't think to examine them for hidden content.
4. It would probably be harder to find original files of child pornography images with which to compare original and modified.
So the two reasons are:
An intensified indoctrination in Islam coupled with the belief that ones soon to be achieved eternal reward will involve lots of sex with virgins and young boys can create a desire for child pornography.
The other is that there are messages hidden in the images.
Though, considering the prevalence of concept of duality in Islamic culture it could also be both at the same time. Messages could be hidden in the child pornography to make them an extra little "perk". This "perk" might be able to then serve as reinforcement (of some sort) of the intensified belief system to remote terrorists who are not in direct contact with the indoctrinators.
