Bug 294485

Application: akonadi_kcal_resource (4.7)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.8.0
Operating System: Linux 3.2.6-3.fc16.x86_64 x86_64
Distribution: "Fedora release 16 (Verne)"

-- Information about the crash:
Added a new calendar (in a vain attempt to make korganiser not read only, but thats another story)
As soon as the calendar was added, and shows as "Ready" in the calendar list the application crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: Calendar of type KDE Calendar (traditional) (akonadi_kcal_resource), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
