Description marek 2017-01-17 18:22:20 UTC
Application: kwin_x11 (5.8.5)

Qt Version: 5.7.1
Frameworks Version: 5.29.0
Operating System: Linux 4.8.15-1-MANJARO x86_64
Distribution: "Manjaro Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I was watching a video and when I pressed custom keyboard shortcut (left arrow) to jump backwards whole screen froze. No mouse was displayed and there was also no sound. The only thing that workded was ctrl+alt+F2 to witch to other terminal. After  switching back video continued to play and whole desktop worked correctly. There was just notification in system tray about crash of Kwin. I am using KDE sping of Manjaro

The crash can be reproduced sometimes.

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

Unfortunately the backtrace is lacking debug symbols. If you are able to 
reproduce please install the debug packages provided by your 
distribution (please ask the distribution support channel on how to 
install them) and attach a new backtrace.
