Bug 254847

Application: kontact (4.4.6)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Using groupdav address book with egroupware.
Tried to sync a todo item to egroupware infolog item.
The todo item was stored locally in another groupdav calendar. It didn't work so I decided to delete the calendar and try try another onther one.
Kontact crashed.

- Unusual behavior I noticed:

Cannot upload tasks/todos using groupdav. to egroupware.

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