Bug 281425

Application: kontact (4.7.0 )
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Kontact crashed when the window was inactive in the background. Second time that happened today. I guess Kmail fetched emails at the crash

The crash can be reproduced some of the time.

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