Could you please attach a backtrace, as explained in:

Comment 2 Dominik Tritscher 2008-07-31 20:15:00 UTC
I can confirm that issue. I tried to get a backtrace (dbg-package for kdegraphics is isntalled) but the crash manager just claimed that the stack frame may have been destroyed.
After running okular from gdb and retrying, I got the following output:

Ah sorry, forgot something important ;)
Here is the rest of the backtrace:

I'm using libpoppler 0.8.3 from Ubuntu packages.
Comment 4 Dominik Tritscher 2008-07-31 20:49:22 UTC
In between I also install libpoppler 0.8.5 and the problem still exists.
Comment 5 Pino Toscano 2008-07-31 21:01:00 UTC
Cannot reproduce with Poppler HEAD.
But anyway, this looks not an Okular problem, but a Poppler one.
Please open a bug report for Poppler at https://bugs.freedesktop.org.

Thanks for your understanding.
