-- Information about the crash:
Akonadi sometimes needs to be restarted (e.g., due to some resource being stuck). I do this using the menu option in akonadiconsole. Often when I do so, kalendarac crashes.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Herinneringen (kalendarac), signal: Aborted
