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

If I close Kontact and immediately start it again, it shows an error, but it starts up anyway and still works fine. But it always gives that error.

The crash can be reproduced every time.

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