           Summary: System Settings crashed when closed with Esc.
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi

          Priority: NOR
         Component: general

Application: systemsettings5 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-28-generic x86_64
Distribution: Ubuntu 15.04

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

Wanted to temporarily turn off the desktop effects. Clicked around a bit in the
Desktop Behavior, Workspace Theme and Display and Monitor but could not find
how. Did not change anything. Closed System Settings using Esc when in the
Display and Monitor view. That's when the Crash Reporting Assistant showed up.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
