Application: korganizer ()

Qt Version: 5.4.2
Operating System: Linux 4.2.0-19-generic x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
- What I was doing when the application crashed:
Toggling calendars off & on with month view open to see which events/todos were associated with which calendar.  After ten to fifteen toggles, korganizer crashes with segV.

- Custom settings of the application:
Multiple calendars - Exchange, Google * 7, Local Todos(Calendar Dir)*4

The crash can be reproduced sometimes.

-- Backtrace:
Application: korganizer (korganizer), signal: Segmentation fault
