Application: plasmashell (5.18.3) Qt Version: 5.14.1 Frameworks Version: 5.68.0 Operating System: Linux 5.5.13-gentoo x86_64 Windowing system: Wayland Distribution: Gentoo/Linux -- Information about the crash: - What I was doing when the application crashed: I had just logged into a Plasma Wayland session, as usual. I finished connecting to a new wireless network using the NetworkManager plasma applet. Shortly after, the screen went black for a few seconds, until the elements of the desktop progressively returned within 10 seconds. The only difference was (a) a new background, automatically refreshed, and (b) KCrash was reporting a crash in the system tray. -- Backtrace: Application: Plasma (plasmashell), signal: Aborted Using host libthread_db library "/lib64/libthread_db.so.1".

Hey Nate, I apologise, I probably should have said so when this appeared to no longer be reproducible. I can't remember the last time I ran into this (being on Gentoo I'm usually on the latest Plasma release immediately). Sorry for holding you up with an old bug!
OK great, thanks!
