Application: kwin_x11 (5.6.4)

Qt Version: 5.6.0
Frameworks Version: 5.22.0
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 had mozilla thunderbird open and wanted to open the web browser to look at something. Kwin crashed when it opened, and then restarted. I had chrome open to the "good news" newsreader app. It doesn't normally cause this problem.

I wanted to attach this to another report but the crash reporting assistant won't let me, so I marked it as a possible duplicate, because I dn't know for sure.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
