Application: kontact (4.7.2)
KDE Platform Version: 4.7.1 (4.7.1)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic i686
Distribution: Ubuntu 11.10

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

I delete a particular mail, then if I want to open another mail, it pause on "Loading mail", but I can try to select another and have the same problem.
So, I close Kontact, no errors.
Reopen it, and the bug appears, If I click "Restart app" or "Close" and restart kontact, everything ok, but, if I try to delete this mail, the same thing appears

The crash can be reproduced every time.

-- Backtrace:
