Qt Version: 4.7.2
Operating System: Linux 2.6.38-02063802-generic x86_64
Distribution: Ubuntu 11.04

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

I added a new event, specified the title as well as the start and end time and when clicking OK Korganizer crashed.

The crash can be reproduced some of the time.
