Bug 244279

Application: kontact (4.4.5)
KDE Platform Version: 4.4.5 (KDE 4.4.5) "release 270"
Qt Version: 4.6.3
Operating System: Linux 2.6.31.12-0.2-desktop x86_64
Distribution: "openSUSE 11.2 (x86_64)"

-- Information about the crash:
My mail server is very slow today. When I click on a mail in my IMAP account, it often takes long before the mail is shown, and often there is a timeout. In this setting, Kontact frequently crashes when downloading mail.

The crash can be reproduced some of the time.

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