Description Eric Armbruster 2024-12-14 20:42:01 UTC 
SUMMARY
Powerdevil loop crashes after login. Also sent some debug info via crash handler to sentry.
Not sure when this started to happen, but I certainly have it since a few weeks and hoped someone else would report it as I am short on time.

STEPS TO REPRODUCE
1. Login to Plasmashell
2. 
3. 

OBSERVED RESULT
In my crashed process viewer I see powerdevil. Bug looks like this is in the qt stack, but then it says

#10 0x00007fa4455b5512 in _dbus_warn_check_failed
    (format=0x7fa4455c11e0 "arguments to %s() were incorrect, assertion \"%s\" failed in file %s line %d.\nThis is normally a bug in some application using the D-Bus library.\n")
    at ../../dbus/dbus-internals.c:289

so reporting here. Thanks!

[UPowerManager] Also print error message on failure

I wonder if it's a coincidence that Solid's `UPowerManager` is showing a disconnection error while the blocked other thread is waiting for

> PowerDevil::BundledActions::PowerProfile::PowerProfile (powerprofile.cpp:44)

(which doesn't use Solid at all) to connect to the same bus.
Comment 7 Nate Graham 2025-05-07 20:54:32 UTC 
Eric, have you seen this again such that you could check the log to see the exact error, due to the logging changes made in https://invent.kde.org/frameworks/solid/-/commit/dec1d165a69a322ae3af5e6f3c24065fcc985276?
Comment 8 Eric Armbruster 2025-05-14 04:54:05 UTC 
No since reinstalling everything is fine. Thanks
