Bug 279717

Application: kontact (4.7.0 )
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:

Kontact crashed when I switched to the Kontact window, which had finished checking mails in the background, by clicking on it (a Firefox window was active before the switch). Kontact was displaying the summary view at the tiem.

The crash can be reproduced some of the time.

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