Bug 363386

Application: plasmashell (5.5.5)
 (Compiled from sources)
Qt Version: 5.5.1
Operating System: Linux 4.1.20-11-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

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

I installed amd driver fglrx. After reboot, as recommended, the plasma crashing.

- Unusual behavior I noticed:

Plasma does not start with AMD drivers fglrx. Was necessary remove fglrx for it back to work.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
