Application: plasmashell (5.17.3)

Qt Version: 5.12.5
Frameworks Version: 5.64.0
Operating System: Linux 5.3.11-300.fc31.x86_64 x86_64
Distribution: Fedora 31 (Thirty One)

-- Information about the crash:
- What I was doing when the application crashed:
I was using Plasma 5.17.3 on Wayland in Fedora 31. I opened Firefox Nightly 72.0a1 on X. I right-clicked near the bottom-right of the screen around where the popup showed Configure Panel. Dr. Konqi appeared in the Task manager, and it showed plasmashell had aborted. The trace had "The Wayland connection experienced a fatal error: %s" in frame #9 in QMessageLogger::fatal of the crashing thread 1.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
