Description Roman 2019-12-06 22:17:55 UTC 
Application: plasmashell (5.17.4)

Qt Version: 5.13.2
Frameworks Version: 5.64.0
Operating System: Linux 5.4.1-arch1-1 x86_64
Distribution: EndeavourOS

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

just switched from an old arch install to a new install of endeavourOs trying to fix this but it continues to plague me.
fresh install of distro and plasma then log into wayland session from sddm to a black screen after a quick flash of my wallpaper or nothing at all.

Eventually logging in just kicks me straight back to sddm but that may a different bug.

The crash can be reproduced every time.

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