Bug 263052

Application: kontact (4.4.9)
KDE Platform Version: 4.5.5 (KDE 4.5.5)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-24-generic x86_64
Distribution: Ubuntu 10.10

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

Kontact was running in the background.  I didn't activate the window since Kontact was launched.


- Unusual behavior I noticed:

On launching KDE Kontact was launched and complained about a possible running other instance of Kontact. As Kontact didn't seemed to be running I confirmed to start Kontact. Short time later it crashed.

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