Bug 200229

Application that crashed: korganizer
Version of the application: 4.3.0 rc2
KDE Version: 4.2.96 (KDE 4.2.96 (KDE 4.3 RC2))
Qt Version: 4.5.0
Operating System: Linux 2.6.28-13-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
STEPS TO REPRODUCE:
1. Have a running korganizer 4.3.0 RC1 calendar set up.
2. Upgrade to 4.3.0 RC2.
3. Run new korganizer.
4. Resources are migrated to akondai.
5. Go to resource view and unselect std.ics, under Akondai compatibility Resource.

EXPECTED BEHAVIOR:

Items associated with this resource would no longer be shown.

ACTUAL BEHAVIOR:

Korganizer hangs for a long time, then crashes.

 -- Backtrace:
