Application that crashed: krunner
Version of the application: 0.1
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-3-amd64 x86_64
Distribution: Debian GNU/Linux 5.0.4 (lenny)

What I was doing when the application crashed:
I tried to start KOrganizer. Waiting for KOrganizer (window) to appear Krunner crashed. Backround information: I had to kill KOrganizer before and had to reboot because the whole system got instable.

 -- Backtrace:
Application: Oberfläche zur Ausführung von Befehlen (kdeinit4), signal: Segmentation fault
The current source language is "auto; currently c".
