-- Information about the crash:
- What I was doing when the application crashed:

I was closing the PDF opened in okular and okular crashed.

Various other informations :
Not very important crash : I would not notice it if I were to disable the crash reporting assistant. Please note that I'm running Gnome. It doesn't reproduce everytime. Okular is always opened from within emacs if that matters.

The crash can be reproduced sometimes.
