Bug 255828

Application: kmail (2.0.89)
KDE Platform Version: 4.5.74 (4.6 >= 20101027) (Compiled from sources)
Qt Version: 4.7.0
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:

KMail had fully expanded one of my IMAP accounts (so all the folders in the treeview were expanded - it does this frequently), so I was going through, rapidly closing them (closing most of the subfolders, then closing the top one).

As I clicked on one of the arrows to collapse a top-level folder, KMail crashed.

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