Summary: chargethresholdhelper crashed in
ChargeThresholdHelper::getthreshold with Plasma 6.1.90
Classification: Plasma
Product: Powerdevil
Version: 6.1.90
Platform: Fedora RPMs
OS: Linux
Status: REPORTED

SUMMARY
I booted the Fedora Rawhide KDE live image
Fedora-KDE-Live-x86_64-Rawhide-20240922.n.0.iso in a QEMU/KVM VM in GNOME Boxes
in a Fedora 41 KDE installation. Plasma 6.1.90 on Wayland started.
chargethresholdhelper crashed twice in ChargeThresholdHelper::getthreshold
during Plasma startup when it was run automatically by
dbus-:1.3-org.kde.powerdevil.chargethresholdhelper@0.service.
Core was generated by `/usr/libexec/kf6/kauth/chargethresholdhelper'.
Program terminated with signal SIGSEGV, Segmentation fault.

The pointers stopThresholdIt and stopThresholds in
ChargeThresholdHelper::getthreshold looked invalid.
(gdb) p *stopThresholdIt
Attempt to take address of value not located in memory.
(gdb) p stopThresholdIt

(gdb) p *stopThresholds

chargethresholdhelper crashed with the same trace when I selected Power
Management in System Settings. This problem happened on 4/4 boots with this
image in VMs and on bare metal. I didn't see this problem with Plasma 6.1.5 or
earlier.
STEPS TO REPRODUCE
1. Boot a Fedora 41 KDE installation
2. Log in to Plasma 6.1.5 on Wayland
3. Download the Fedora Rawhide KDE live image
Fedora-KDE-Live-x86_64-Rawhide-20240922.n.0.iso from
https://koji.fedoraproject.org/koji/buildinfo?buildID=2550880
4. Install GNOME Boxes if it isn't already with sudo dnf install gnome-boxes
5. Start GNOME Boxes
6. Boot Fedora-KDE-Live-x86_64-Rawhide-20240922.n.0.iso in a QEMU/KVM VM in
GNOME Boxes
OBSERVED RESULT
chargethresholdhelper crashed in ChargeThresholdHelper::getthreshold with
Plasma 6.1.90
EXPECTED RESULT
chargethresholdhelper shouldn't have crashed
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora Rawhide/42
KDE Plasma Version: 6.1.90
KDE Frameworks Version: 6.6.0
Qt Version: 6.7.2
