KDE Platform Version: 4.6.5 (4.6.5)

Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
I finished writing an email, then I clicked send button. The window became gray, but then it freezes : the message window stayed green and only the close/minimise button from the window manager were accesible. Clicking close crashed kmail.

This appends from time to time.

The crash can be reproduced some of the time.

-- Backtrace:
