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

I created new email template in kmail settings and then after I closed KMail it refuses to start again and always crashes with attachted backtrace.

Also, kontact won't start either

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Aborted
