-- Information about the crash:
- What I was doing when the application crashed:
I received an email and got notified about it. The mail was in a sub-folder of my account. When I clicked on that folder Kontact crashed.
After restarting Kontact, I clicked on the same folder and on the new mail. No crash this time.

The crash does not seem to be reproducible.
