Application that crashed: kontact
Version of the application: 4.3.0
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.29.6-tp42-toi-3.0.1-01085-gf325e4a i686
Distribution: Debian GNU/Linux 5.0.1 (lenny)

What I was doing when the application crashed:
Kontact crashed on exit. I was reading news in Akregator, but AFAIR I had KMail open at the time on exit. The backtrace points towards kmail as well.

I have no idea on how to reproduce this however. It was the first crash of Kontact on exit since a long time.

I am using Debian squeeze / sid packages:
