-- Information about the crash:
I booted the Fedora Rawhide KDE live image
Fedora-KDE-Desktop-Live-Rawhide-20250212.n.0.x86_64.iso on bare metal. Plasma
6.3.0 on Wayland started. I clicked on the Networks icon in the system tray a
few times. plasmashell crashed the third time the Networks applet was shown.
plasmashell crashed sometimes in QSharedPointer<NetworkManager::Device>::deref
with what looked like an invalid pointer this=0x11 in frames 4 to 8. The trace
was similar but different at its top to the one at
https://bugs.kde.org/show_bug.cgi?id=499218 The problem might be due to a GCC
15 problem with C++ coroutines https://bugs.kde.org/show_bug.cgi?id=499218#c4
The crash can be reproduced sometimes.
