Description Scott 2018-01-15 07:32:40 UTC

Application: plasmashell (5.11.5)

Qt Version: 5.10.0
Frameworks Version: 5.41.0
Operating System: Linux 4.14.13-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed: Clicking the show desktop icon does nothing, clicking the edit taskbar causes the taskbar and KDE to crash. My kernel is not tainted and I have not done anything other that using wayland and installing a few packages. I just installed Arch less than 12 hours ago. 

- Unusual behavior I noticed: Show desktop fails and some strange display artifacts sometime appears. I am using Wayland and I believe this to be highly relevant.

The crash can be reproduced every time.

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