Bug 207046

Application that crashed: kontact
Version of the application: 4.3.1
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-15-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
Kmail crashes when sending or receiving email. Not every time, rather randomly. I don't know how to reproduce. I haven't tried yet to run kmail standalone, only in kontact.

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