Application: kontact (4.9)
KDE Platform Version: 4.9.00 (Compiled from sources)
Qt Version: 4.8.2
Operating System: Linux 3.5.3 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
I'm using google calendar.

- What I was doing when the application crashed:
First I created a new regular appointment with 2 alarms and kontact crashed. When opened again the appointment was duplicated. From that moment, everytime I try to edit an event (anyone) kontact crashes with the previous backtrace.

The crash can be reproduced every time.

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