Application: kmail (2.0.89)
KDE Platform Version: 4.5.67 (4.6 >= 20100901) (Compiled from sources)
Qt Version: 4.6.3
Operating System: Linux 2.6.35-ARCH x86_64
Distribution (Platform): Archlinux Packages

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

I was going through the folder tree, collapsing folders (because KMail sometimes expands the whole tree), and accidentally selected about 10 folders at once.  I continued collapsing these folders, then clicked on another (unselected) folder.  Then KMail crashed.

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