Application: kmail (4.7.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.2.0-5-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed: Kmail was in the background, but hanging on a folder. I read that there is a bug, which might be related to this. But this bug should be fixed in KDE 4.7.4. Since I am running 4.7.4 it either is not fixed or not related.

- Unusual behavior I noticed:
I was just finishing bug report https://bugs.kde.org/show_bug.cgi?id=289198 which had occured before, so they may be related.

-- Backtrace:
Application: KMail (kmail), signal: Aborted
