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 moved a lot of messages (not sure how many, over 100 though) from a folder to its parent, then deleted the original folder.  The message list pane looked like it was still viewing the old folder with all the (now moved) messages in, and an unrelated IMAP account (not a folder, the account itself) was selected in the folder tree.  I clicked on the folder I had moved the messages to, and KMail crashed.

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