Bug 290793

Application: kmail (4.8 rc1)
KDE Platform Version: 4.7.95 (4.8 RC1 (4.7.95)
Qt Version: 4.7.4
Operating System: Linux 3.2.0-7-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed: The crash occured when I closed Kmail because Kmail was not working correctly. It did not show the content of the Inbox folder (IMAP) while it was able to show the content of all other folders of that account.

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