Bug 290208

Application: kontact (4.7.3)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.2.0-rc7 x86_64
Distribution: "Gentoo Base System release 2.0.3"

-- Information about the crash:
- What I was doing when the application crashed:

I added my GMail account as imap resource to kmail. Everything synced fine for minutes over minutes but then stopped syncing in a very big gmail folder (18000+ mails). I tried to stop the sync action using the activity popup in the lower right corner. It hung. KMail, however, continued to work just fine on existing folders and other imap accounts.

I then tried to exit kmail and it crashed.

The crash can be reproduced some of the time.

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