Bug 309663

Application: kontact (4.9.2)
KDE Platform Version: 4.9.2
Qt Version: 4.8.3
Operating System: Linux 3.5.0-17-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
Kontact has suddenly started crashing everytime I try to send an email from Kmail.  I have logged out then back in again and even rebooted the machine.  It's not tied to addressee (I've tried numerous different ones).  The mail server is fine (I sent an urgent email using another machine that uses the same server from the same subnet).  Kmail and Kontact have previously worked fine.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Bus error
