Application: plasmashell (5.11.4)

Qt Version: 5.10.0
Frameworks Version: 5.41.0
Operating System: Linux 4.14.9-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
Changing Chromium playback output in Audo Volume Settings to headphone jack
- Unusual behavior I noticed:
Previously today I had used xkill to kill Plasma. I then rebooted.

The crash does not seem to be reproducible.

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