Bug 296145

Application: kmail (4.8.0)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.0.0-17-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed: Advancing through list of emails

Notes:

1. I've had a lot of crashes in kmail recently.  Today I had two within five minutes.

2. Since there's no clear action that triggers this bug, there's no way to know if it's a true duplicate of any other kmail bug.  As far as I know I was not doing anything that I haven't already done successfully many times.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
