Bug 304109

Application: korganizer (4.8.4- ())
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-27-generic x86_64
Distribution: Ubuntu 12.04 LTS

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

Changed current view filter from all except two categories to only one category.  Closed window with OK.  View appeared not to change to match current definition of filter.  Used menu to set 'No filter'; then immediately went back and set to the previous filter.  Crash.

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