Application: kmail (4.8.5)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-35-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

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

I was moving email between two local folders. I had successfully moved a large number between various folder but was getting impatient and tried starting a new move operation before the last one completed. Bam! Seg fault. The emails were imported from Outlook, through Thunderbird in Windows, then into Kmail but that probably does not matter.

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