-- Information about the crash:
- What I was doing when the application crashed:
I had a half written mail, started  writing in the "TO" field. Autocompletion popped up.
I continued writing the name, KMail crashed.
Happened twice, haven't tried more times.

Special setup:
Akonadi using postgresql.

The crash can be reproduced every time.

Update : it doesn't happen on every contact (or at least not for the matches I tried). I have one contact with which it happens every time.
