Application: kontact (4.7.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.8.0
Operating System: Linux 3.1.6-1.fc16.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

1. Clicked message on the list
2. Hit 'a' on keyboard | clicked on 'Replay to all' in Kmail main window | clicked on 'Replay to all' in message window
3. KMail crashes

After KMail/Kontact restart: appeared main KMail/Kontact window with additional window for message writing with message thread (just like I'd clicked reply), but with no signature and all the text was wrapd at ~5-7th column. When I've done the same (1-3), without closing reply window, Kontact/KMail crashed and after restart there was: windows from last 'session' (main + reply) + nest replay window, also without signature and with strangely wrapped quote text.

In my customized templerates I've put literally %SIGNATURE and checked option 'Automatically add signature' <- maybe this was the problem, because when I've restored default email templates (for replying) KMail stopped crashing.

The crash can be reproduced every time.
