Application: kontact (4.4.10)
KDE Platform Version: 4.5.5 (KDE 4.5.5) "release 1"
Qt Version: 4.7.2
Operating System: Linux 2.6.34.7-0.7-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
Kontact threw a crash report that I did not report so I am not sure what happened.  However when I tried to restart Kontact it kept saying that another Kontact session was already running.  I am submitting the crash report from that message.

The crash can be reproduced every time.

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