Description Kelvie Wong 2009-10-19 23:38:00 UTC 
Application: okular (0.9.80)
KDE Version: 4.3.72 (KDE 4.3.72 (KDE 4.4 >= 20091015)) (Compiled from sources)
Qt Version: 4.6.0
Operating System: Linux 2.6.32-rc2-00301-gf0a221e x86_64
Distribution: "Gentoo Base System release 2.0.1"

What I was doing when the application crashed:
The backtrace is attached, I just turned off the table of contents sidebar, resized the window, and scrolled down again.

The PDF I used was this one, if it matters:

Sadly this backtrace is not of much use, i doubt we can make much use of it :-/ but thanks for the report

"malloc_printer" could be related to bug 196207.
If you can reproduce this crash all the times, can you try running Okular using the command "MALLOC_CHECK=   okular" from Konsole and checking if it also crashes ? 
Thanks
