Power management page crash info
SUMMARY
Power Management seems entirely broken on Fedora 41 after the 6.3.0 update.
Fedora uses tuned for handling power profiles and its logs show clear problems:
Log file at /var/log/tuned/tuned.log shows an error when plasma components
attempt to query battery and power profile information.
Here is a small snippet of the log:
```
2025-02-12 17:02:06,484 INFO tuned.exports.dbus_exporter: action
'org.freedesktop.UPower.PowerProfiles.switch-profile' requested by caller
':1.69' wasn't authorized, ignoring the request
2025-02-12 17:02:08,698 INFO tuned.exports.dbus_exporter: action
'org.freedesktop.UPower.PowerProfiles.switch-profile' requested by caller
':1.94' wasn't authorized, ignoring the request
2025-02-12 17:02:15,659 INFO tuned.exports.dbus_exporter: action
'org.freedesktop.UPower.PowerProfiles.switch-profile' requested by caller
':1.111' wasn't authorized, ignoring the request
2025-02-12 17:02:22,123 INFO tuned.exports.dbus_exporter: action
'org.freedesktop.UPower.PowerProfiles.switch-profile' requested by caller
':1.121' wasn't authorized, ignoring the request
```
Power management page in system settings crashes the whole app. The crash info
has been added as an attachment.
Plasmashell battery widgets doesn't show battery percentage or anything else
related to power profiles or battery and claims its not supported.
STEPS TO REPRODUCE
1. Get KDE Plasma on Fedora 41 with tuned in use on a device with battery and
power profiles support
2. Try interacting with power management features in plasma
3. Observe broken behavior
OBSERVED RESULT
Nothing related to power management works on the laptop
EXPECTED RESULT
Power management allows me switch profiles, set up automatic behaviors, see
battery percentages and else
