Application: kwin_x11 (5.8.4)

Qt Version: 5.7.0
Frameworks Version: 5.29.0
Operating System: Linux 4.8.14-1-default i686
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed: booted to level 3, init 5, chose a KDE plasma failsafe session, logged in. Screen went dark and then backlit (not so dark) I think. Previous attempts at Plasma 5 sessions noted crash putting up welcome screen and then crash starting plasma session. Could not find core dump.

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
