Bug 296993

Application: akonadi_kolabproxy_resource (4.8)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I changed an event and pressed RMB+resync on Korganizer-kpart in Kontact
Restart of ressource seems to lead to duplicates of events in akonadi cache but not on server(!)

The crash can be reproduced every time.

-- Backtrace:
Application: Kolab vom Typ Kolab Groupware-Server (akonadi_kolabproxy_resource), signal: Segmentation fault
