Application: kwin_x11 (5.8.3)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.6.2-4.g14295d6-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
This is first time it crashed on login for me. I did not update or install any new packages  from the last login, which succeeded without crash. May be a clue that before last shutdown I was playing with QMidiArp \ Carla \ Yoshimi. Also this time the Claudia did not start on boot (ususally it does start), despite the fact that it is in the "Autostart" in KDE systemsettings.

The crash can be reproduced sometimes.

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