           Summary: Plasma 5.2 System Preference Crash
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general

Application: systemsettings5 (5.2.0)

Qt Version: 5.4.0
Operating System: Linux 3.16.0-30-generic x86_64
Distribution: Ubuntu 14.10

-- Information about the crash:
- What I was doing when the application crashed: I opened the "Display and
Monitor" system settings. It showed a wrong resolution for both of my two
monitors, connected via HDMI and DVI. I didn't change any setting and cancelled
the dialog. Immediately afterwards, Plasma showed a crash notification and
terminated the complete System Settings dialog.

I run Kubuntu 14.10 64bit and the latest Plasma 5.2, upgraded via "sudo apt-get
upgrade". I am using an NVIDIA GT220 graphics card.

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