--- Comment #5 from Matt Fagnani <matt.fagn...@bell.net> --- Created attachment 178676 --> https://bugs.kde.org/attachment.cgi?id=178676&action=edit plasmashell 6.3.1 trace I was using Plasma 6.3.1 on Wayland in a Fedora Rawhide live image on bare metal. I clicked on the Networks icon in the system tray repeatedly. plasmashell crashed in QSharedPointer<NetworkManager::Device>::deref with a trace like I reported here.
