Bug 252373

Application: kontact (4.4.2)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-24-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
This happens about 50% of the time. When I close Kontact and later try to open it agan it either won't open (The icon bounces and a program tag opens at the bottom but after a bit both close and either nothing happens at all or I get a crash report. However either way, if I go to System Activity Kontact is still listed as a process and if I force kill it it will load normal next time it's clicked. If I go to System Activity right now, even after this crash report, it shows Kontact as "stopped". 

The crash can be reproduced some of the time.

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