Bug 313143

Application: korganizer (4.9.3)
KDE Platform Version: 4.9.3
Qt Version: 4.8.3
Operating System: Linux 3.5.0-21-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
Iterating down the list of my local and WebDAV calendars, disabling them to minimize the events shown while I dealt with one particular calendar.  Got to a local calendar after closing a WebDAV calendar and when I disabled the local calendar, Korganizer seg faulted

The crash can be reproduced every time.

-- Backtrace:
Application: KOrganizer (korganizer), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
