Description Elias Probst 2009-08-25 03:20:56 UTC 
This KDE bug is according to Pino Toscano an upstream issue:
https://bugs.kde.org/show_bug.cgi?id=205056

Quote from the bugreport:
Only white pages are displayed + this error is displayed endless times on the
terminal, when starting Okular from a terminal:
Error: read error: passed the end of the codestream (start = 268808272, current
= 268811780, end = 268811780

The numbers in the error don't change, they're always the same.

While this happens, the CPU usage of one core goes to ~80% (Intel Core 2 Duo,
T7400 @ 2.16GHz).

It only happens, when trying to open this PDF:

Used poppler version: 0.10.7

The problem is that the OpenJPEG based JPXStream decoder feeds the OpenJPEG library the data and it loops forever there, i've contacted the OpenJPEG people to see if they can fix it.

Thanks for responding so fast.
Let's see what the OpenJPEG guys find out.
