Description Andreas 2014-03-26 10:20:01 UTC 
Application: kontact (4.11.5)
KDE Platform Version: 4.11.5
Qt Version: 4.8.5
Operating System: Linux 3.11.10-7-desktop x86_64
Distribution: "openSUSE 13.1 (Bottle) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I have a (weekly) series of calendar events. One of them exceptionally takes place at a different location. In order to manipulate that one exceptional event I tried to dissiciate it from the series. 

Kontact deleted the whole series of events, and then complained twice with an error dialog that it couldn't remove the event, because it didn't exist. Then it crashed.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Andreas 2014-03-26 10:22:48 UTC 
After restarting Kontact, the event is still there. So, it hasn't been deleted after all. However, when I try to dissociate the event again, the same crash as above happens.

Some more details:
This time the error message about ~cannot delete non-existing event~ popped up only once. The whole series of events vanished from the calendar views, but the program still ran. Only after I clicked on a different day in the calendar view did Kontact crash.
