-- Information about the crash:
I booted the Fedora Rawhide KDE live image
Fedora-KDE-Desktop-Live-Rawhide-20250123.n.0.x86_64.iso on bare metal. Plasma
6.2.90 on Wayland started. I clicked on the Screen Brightness icon in the
System Tray. I set the screen brightness to 20% and the Night Light to on at a
manual location. 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 screen went black. plasmashell disappeared and reappeared
automatically. drkonqi showed that plasmashell aborted with a malloc error in
frame 10 in malloc_printerr "malloc(): unaligned tcache chunk detected" of the
crashing thread 1. Functions like in QMap<QString, QVariant>::insert in
/usr/lib64/qt6/qml/org/kde/plasma/private/batterymonitor/libbatterymonitorplugin.so
were lower in the trace.
plasmashell crashed with the same sort of trace when I clicked on the Networks
icon in the System Tray again. I didn't see this problem with 6.2.5 or earlier.
The crash can be reproduced sometimes.
