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

The crash occures after dragging a contact from kaddressbook component into the *body* of new message editor.

Steps to reproduce:
1. Open new message composer
2. Drag a contact from kaddressbook component into the *body* of composer
3. Immediate crash

The crash is also reproducible on standalone kmail and kaddressbook.

The crash can be reproduced every time.
