Application: kwin_x11 (5.5.4)

Qt Version: 5.5.1
Operating System: Linux 4.1.15-8-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

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

I click on a favorite icon in the KDE menu.  The crash happens immediately after main window of the launched application gets painted, and before I have any interaction with the application.

It does not appear to matter _which_ favorite I have launched: The crash has happened after launching firefox, chromium, konsole and a shell script that starts an app in wine, but does not happen consistently with any of these.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
