-- Information about the crash:
I booted the Fedora Rawhide KDE live image
Fedora-KDE-Desktop-Live-Rawhide-20250127.n.0.x86_64.iso on bare metal. Plasma
6.2.90 on Wayland started. I clicked on the Networks icon in the System Tray.
I clicked on the Bluetooth icon in the System Tray. I disabled Bluetooth from
the Bluetooth applet. I clicked on the Networks icon in the System Tray. The
Networks applet appeared and froze midway through a sliding to the left
animation. plasmashell disappeared and reappeared automatically. plasmashell
crashed in std::__atomic_base<int>::fetch_sub with a segmentation fault. The
trace was different from the crashes I reported at
https://bugs.kde.org/show_bug.cgi?id=499081 The crash didn't happen when I
clicked on the Networks icon a couple more times.
The reporter is unsure if this crash is reproducible.
