Application: kwin_x11 (5.8.3)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.36-8-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
- What I was doing when the application crashed: Clicked a desktop widget to open Quicken 2016 with cxoffice.  Quicken did open and kwin restarted on it's own.  Currently running SUSE Leap 42.2 with plasma 5

The crash can be reproduced sometimes.

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