Application: kontact (4.4.5)
KDE Platform Version: 4.4.95 (KDE 4.4.95 (KDE 4.5 >= 20100723))
Qt Version: 4.6.3
Operating System: Linux 2.6.34-12-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Browsing the internet with Firefox. 

KMail just crashed after ~5 minutes. This has happened a few times, but it seems only once per session. After I restart Kontact I don' get another crash until I login to KDE again (however this may be random) If the crash occurs It happens the first 15 minutes I'm logged in.

The crash can be reproduced some of the time.

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