Application: kmail (4.8.2)
KDE Platform Version: 4.8.2 (4.8.2) "release 494"
Qt Version: 4.8.1
Operating System: Linux 3.1.10-1.9-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

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

I wanted to switch my message list to a new folder that I have in my favorites area (this folder also belongs to a different account) and KMail crashed.

Both accounts are disconnected IMAP accounts, I also have a POP one configured though I rarely switch to it.

KMail has crashed before, though I can't remember if it was on folder switch or not.

The crash can be reproduced some of the time.

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