Bug 252060

Application: akonadi_kcal_resource (0.1)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic x86_64
Distribution: Ubuntu maverick (development branch)

-- Information about the crash:
- Custom settings of the application:
I have a remote calendar (.ics) on a server accessible via ssh. I am using the compatibility resource.

Whenever I am offline, the relevant akonadi resource crashes. Removing the calendar stops the crashing.

The crash can be reproduced every time.

-- Backtrace:
Application: Akonadi Resource (akonadi_kcal_resource), signal: Segmentation fault
