Application that crashed: kontact
Version of the application: 4.3.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic x86_64

What I was doing when the application crashed:
Kontact seems to crash on exit if it was started at login. Crash is reproducable but I can't confirm it happens 100% of the time.

 -- Backtrace:
