Distribution (Platform): Fedora RPMs

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

1. Open KMail
2. Press check mail button
3. Wait
4. Go through folders and look at some unread messages in the preview pane
5. Quit KMail
6. Get a DrKonqi notification about it crashing

The crash can be reproduced sometimes.
