Application: kontact (4.8.2)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Moving a folder in kmail.
This doesn't occur with every attempt to move a folder, but has happened several times.
After restarting Kontact, it appears that the folder was moved as intended.
This is a fresh install of Kubuntu 12.04, Kontact 4.8.2.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
