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

I wrote an email and tried to send it. The Window become grey, and it froze. This happens vesy often, but not always I send an email (I don't know the reason). After seconds without getting an answer, I closed the window, and Kmail crashed.

The crash can be reproduced some of the time.
