PDFParser does his job correctly.
The problem is that the parser under some circumstances read some garbage data as the key. That's the reason why the script stops.

I would be interested to communicate with a pdf expert. I've got the knowledge over the script and he/she would have deep pdf format knowledge.

But I suppose that won't be happening so the only possible solution is to get more pdf knowledge and do it yourself.

Anyway, I have to say that ILC has made a very good job - there is a lot of deep knowledge in the script. I suppose he was/is in a pdf related job anyway.
