Description billrclarity 2017-03-29 07:50:39 UTC
Application: kwin_x11 (5.8.6)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.49-16-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
- What I was doing when the application crashed:
Clicked on the luckybackup window to load the manage backup window.   Screen blinked and error message appeared saying KWIN crashed.  Appears to have restarted normally as I was able to operate crash assistant.

The crash can be reproduced sometimes.

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