Application: korganizer (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-13-generic x86_64
Distribution: Ubuntu 13.10

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

Korginizer failed when I pressed "Apply" in its settings.
There were several recurring tasks modifications. Guess, this is usefull note as I see the stack in a thread is pointing to hasRecurrenceId().
As DAV source I'm using my own DaviCal instance on a server near me (1 meter or less, direct ethernet link).

-- Backtrace:
