Application: kontact (4.8.0)
KDE Platform Version: 4.8.00 (4.8.0
Qt Version: 4.7.4
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I just rebooted my PC cuz I was doing some OGL stuff that crashed KDE and everything and after the reboot my session was restored and I wanted to minimize (systray) kontact and clicked X while the organizer reminder daemon was still loading - maybe that has something to do with it.

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