Bug 296353

Application: kontact (4.8.0)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.3.0-030300rc7-generic x86_64
Distribution: Ubuntu precise (development branch)

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

I've written my e-mail than after pressing the send button (set to send now). Editor (default) window greys out and nothing more happens.
I have PGP enabled for my email so I expected the PGP password entry window to show but that does not happen. If then I switch to kontact main window and close it (editor window stays grey - I'm not cancelling my preciuos already typed in mail). Kontact end with this crash. After reopening Kontact my prepared mail pops up (editor window) so at least I can copy it's content and sent it using another client.
I'm not sure but it's possible that I can send only one mail using Kontact/KMail after starting my System after that one mail next ones are as described above.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
