-- Information about the crash:
- What I was doing when the application crashed: Clicked on a mailto button
from a chrome page.

- Unusual behavior I noticed: KMail was already launched and running and it
crashed immediately.

- Custom settings of the application: None.

The reporter is unsure if this crash is reproducible.
