Bug 266177

Application: kontact (4.4.9)
KDE Platform Version: 4.6.00 (4.6.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.37-020637-generic x86_64
Distribution: Ubuntu 10.10

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

Replying to an email in an IMAP folder, when I hit send I got the segmentation fault.

I'm also getting crashes on exit, but I don't have a backtrace to hand to compare with this (will try and reproduce).

I've selected an existing bug as a potential duplicate, the stack trace looks very similar but I'm not completely convinced it's the same issue.

The crash can be reproduced some of the time.

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