Sentry Crash Report:

Description Kévin Le Gouguec 2024-07-08 12:16:30 UTC 
Application: org_kde_powerdevil (6.1.2)

Qt Version: 6.7.2
Frameworks Version: 6.3.0
Operating System: Linux 6.9.7-1-default x86_64
Windowing System: Wayland
Distribution: "openSUSE Tumbleweed"
DrKonqi: 6.1.2 [CoredumpBackend]

-- Information about the crash:
If I remember correctly, I picked the mouse after a period of inactivity (possibly after toggling my KVM switch back to this desktop) and started moving the pointer toward the system tray, then the crash notification came up.

I do not think any GUI application were running, but I might be misremembering (memory of the incident got hazy after some roundtrips through zypper to install debug info & python311-sentry-sdk).

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: KDE Power Management System (org_kde_powerdevil), signal: Segmentation fault
