Bug 248650

Application: kmail (1.13.2)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-24-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
If kmail has been open continuously for several days, it often becomes unresponsive, and then crashes instead of exiting cleanly when I try to kill it to free up resources.

The crash can be reproduced some of the time.

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