Application: kontact (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.2
Operating System: Linux 3.2.0-54-generic x86_64
Distribution: Ubuntu 12.04.3 LTS

-- Information about the crash:
- What I was doing when the application crashed: I quit the application at which the point it crashed. Prior to that I cancelled some ( I don't know if all) folder-sync operation, they seemed to be hanging. I don't know if that has something to do with it, though.

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