Application: kontact (4.7.0 )
KDE Platform Version: 4.7.00 (4.7.0) "release 6"
Qt Version: 4.7.3
Operating System: Linux 2.6.37.6-0.7-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
First I changed a few settings under "Settings: Configure Kontact"
That seemed to work. Then I choose the first goup of settings to automatically start Calendar if Kontact is started. 
After I made the "Apply", Kontact crashed.

Now every time (three times in a row) I go in Kontact to "Configure Kontact", Kontact crashes.
I can however go to the sub-parts: "Configure Calendar" and change those.

KDE comes from the openSuse repros.

The crash can be reproduced every time.

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