Description Laszlo Stark 2018-01-10 07:50:17 UTC 
Application: plasmashell (5.11.3)

Qt Version: 5.9.3
Frameworks Version: 5.40.0
Operating System: Linux 4.14.12-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

I wanted to hide the 'davmail' icon from the system tray in my standard panel. When I changed the visibility of said icon in the system tray settings from 'Auto' to 'Hidden', all my windows and my panel disappeared. It didn't throw me back to the tty but started plasma again, just about a second later. All the windows that I had open before the crash also appeared again.

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