Description lhaastdaiz 2017-05-25 12:43:53 UTC
Application: kwin_x11 (5.9.5)

Qt Version: 5.7.1
Frameworks Version: 5.33.0
Operating System: Linux 4.8.0-52-generic x86_64
Distribution: KDE neon User Edition 5.9

-- Information about the crash:
KWin crashed while switching Window Decoration themes. I believe the crash occured while I switched from the Air-Oxygen theme to the Plastik theme.

I tried to recreate the crash but was unable to, and I couldn't find kwin-x11 debug symbols so they weren't included.

The crash does not seem to be reproducible.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

As a workaround use the breeze window decoration.
