Bug 354514

Application: systemsettings (4.11.20)
KDE Platform Version: 4.14.9
Qt Version: 4.8.6
Operating System: Linux 3.16.7-24-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
Preliminary Information
------------------------------------
3-monitor setup on 2x (Crossfire disabled), W7000 Firepro adapters. 
Installed "amd-driver-installer-14.502.1040-x86.x86_64" using the Open repo.

Lead-in
------------------------------------
After orienting the displays in CCC and allowing dragging across monitor frames, subsequently requiring reboot, any launch of CCC or KDE configurator for display properties thereafter yields inconsistent results.  

Observation 1: KDE's "Configure Desktop" > "Display and Monitor" option now only shows 1 montor detected, although all monitors are currently displaying single desktops.  

Observation 2: AMD CCC (both Administrative and non) crashes after timeout.  

Lead-out
------------------------------------
No additional configuration is possible now via either method.

The crash can be reproduced every time.

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