Application: kontact (4.4.2)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-25-generic i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
I pressed "x" (close) in the upper right corner of the Kontact window. Kontact closed, but the error reporting assistant appeared, despite the fact that I didn't notice any problems. However the application probably crashed while closing it...

The crash does not seem to be reproducible.

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