Bug 364161

Application: systemsettings (4.11.20)
KDE Platform Version: 4.14.9
Qt Version: 4.8.6
Operating System: Linux 3.16.7-21-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Return from System lock, system set to lock after 5 minutes, password required.

- Unusual behavior I noticed:
Only primary monitor displaying.  Used system settings to turn second monitor back on after manual restart of monitor via power button.

- Custom settings of the application:
Duel monitors.

The crash can be reproduced sometimes.

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