Bug 250552

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 i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
I was trying to open the folders of my mail-account. This time Kmail crashed while loading the contents. It sometimes crashes too while opening a mail or deferring mails from the inbox into another folder. The imap server seems to work very slow and loading the contents needs almost all RAM.

The crash can be reproduced some of the time.

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