Bug 379067

Application: kwin_x11 (5.9.4)

Qt Version: 5.8.0
Frameworks Version: 5.33.0
Operating System: Linux 4.10.10-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Suspended the laptop, then woke it from hibernation. Lock screen appears, I input my credentials successfully. Kwin appears crashed (No menu bars anymore) and the crash reporting assistant window appears.

This was observed in a multi-screen setup (2 external monitors connected via a Thinkpad dock and DP).

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
