-- Information about the crash:
- What I was doing when the application crashed:

I selected the calendar.

Calendar starts to build up the view, but Kontact crashes before it gets very far.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
