Version:           4.2 rc1 (using Devel)
OS:                Linux
Installed from:    Compiled sources

I'm using the recent KDE 4.2 RC Kubuntu packages.

I set KOrganizer's "Akonadi Compatibility Ressource" to use an *.ics file I copied from another computer's KOrganizer to my home folder, and KOrganizer crashed. (see attachment #1 [details])

After restarting the program, all calendar entries where imported. When I tried to create a new entry, it crashed again, this even akonadi_ical_resource, too. (see attachment #2 [details])
On the console it said:
