Bug 289028

After the last update karm crashes immediately.
Removing .kde/share/apps/karm/karm.ics lets karm start but trying to save a new task karm crashes again.

Steps to reproduce: 
Install opensuse 10.2 with KDE, install kdepim3-time-management. Start and use "karm". 
Update, start "karm" again and see how it crashes.
Remove .kde/share/apps/karm/karm.ics and start karm. Try to create a "New Task" and see the crash happen.

Backtrace of karm:

(gdb) run
