Application: kmail (4.9.5)
KDE Platform Version: 4.9.5
Qt Version: 4.8.3
Operating System: Linux 3.5.0-34-generic x86_64
Distribution: Ubuntu 12.10

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

I think i tried answering an email by clicking the reply button. 
Kmail crashed and didn't come up again. Afte reach start it hangs until timeout.

I think also i got some Qt related errors starting in the console.

It's possible that the html part of the shown message included something strange, maybe its an akonadi problem?

The crash can be reproduced every time.
