Application: kontact (4.7.3)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-15-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
Kontact was opened for few minutes/hours. I closed it but it was still running according to ps -aux (or any monitoring application), but no window opened or tray icon.
When I started Kontact again, it crashes.

Actually, it crashes everytime it doesn't close properly before, but I can't reproduce the unfuntionnal closing. Maybe related to the calendar part of Kontact, as it doesn't display all of the "view" buttons (months, weeks...) before it doesn't close properly.

- Unusual behavior I noticed:
Kontact doesn't not totally close before crashes.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
