Bug 243410

Application: kmail (1.13.5)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-23-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Sometimes (not always) kmail crashes when I delete mutliple emails in an imap folder. It seems to crash when there is still another process going on, like fetching email or performing another delete.

The crash can be reproduced some of the time.

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