Bug 309021

Application: kontact (4.9.2)
KDE Platform Version: 4.9.2
Qt Version: 4.8.3
Operating System: Linux 3.5.0-18-generic x86_64
Distribution: Ubuntu 12.10

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

The app was just open - I guess it was either synchronizing with my ownCloud instance or fetching mail.
The BT looked suspeciously much like the suggested duplicate which is marked as fixed in 4.8.(4?)

-- Backtrace:
Application: Kontact (kontact), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
