Bug 267999

Application: kontact (4.4.9)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic-pae i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
It was after a clean log on and no other program running.
Also all my machines (5) report problems with Nepomuk and errors on Mysql.
Cannot access egroupware with groupdav feature.

The crash can be reproduced every time.

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