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:
In the Todo view of KOrganizer, started independently, not from Kontact.  Filter view active, which included hiding completed items.  Set percent complete for several items using right click and selecting %.  Clicked on checkbox of another item to mark complete.  Dialog box started to come up and the application crashed.

Touchpad disabled in X:
xinput --set-prop "AlpsPS/2 ALPS DualPoint TouchPad" "Device Enabled" 0
Using USB mouse instead.

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