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
$2 = <optimized out>

(gdb) p stopThresholds
$1 = {d = {d = 0x55c56f2fadd0}}
(gdb) p *stopThresholds
Attempt to take address of value not located in memory.

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

ADDITIONAL INFORMATION
Comment 2 Natalie Clarius 2024-09-23 18:44:54 UTC
That's weird, we have a check in place to ensure that a threshold does exist so I currently don't see how it can reach that point without having a value.
Comment 3 Marco Martin 2024-09-24 09:14:03 UTC
does thins happen only when running on a VM?
Comment 4 Matt Fagnani 2024-09-24 16:44:18 UTC
I've seen this problem on bare metal as well as I mentioned. The threshold might have been set but the pointer stopThresholdIt might've been corrupted or pointed to an inaccessible address. I looked at a few of the reports in the search of Nate in comment 1, but I didn't see ChargeThresholdHelper::getthreshold in their comments. When I searched for ChargeThresholdHelper::getthreshold nothing was found a couple days ago. Thanks.
Comment 5 Geraldo Simião 2024-09-24 19:54:09 UTC
Same is happening with my baremetal installation after upgrade to 6.1.90
