Description Achilleas Pipinellis 2019-12-16 10:01:24 UTC

Application: plasmashell (5.17.4)

Qt Version: 5.13.2
Frameworks Version: 5.64.0
Operating System: Linux 5.4.2-arch1-1 x86_64
Distribution: "Arch Linux"

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

I unplugged the external monitor from my laptop which I had hooked up with a display port ( I think the same happens with HDMI).

The crash can be reproduced sometimes.

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