Application: kontact (4.4.6)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.36-020636-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed: Tried to start Kontact.

I clicked the kontact button; nothing happened, so I tried again. And after trying one more time, the crash dialog appeared. While filling in the this dialog, I tried it again (after installing the 
kdepimlibs-dbg  and kdepim-dbg packages), and it started just fine.

This is on Kubuntu 10.10.

The crash can be reproduced some of the time.

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