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

I had moved 4 folders simultaneously into another and KMail crashed immediately 
afterwards. After restarting KMail, the folders were all at the new location, complete with subfolders.

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