Issue

I am not quite sure if this is directly related to cinnamon-settings-daemon since some other sources also seem to be triggering the lines, but linuxmint/cinnamon#11086 directed me here :)
Also, most of the log spam stems from cinnamon-settings-daemon, so it is at least mildly related.

I am getting the following line spammed in my ~/.xsession-errors:

(csd-power:2327): GLib-GIO-CRITICAL **: 11:25:47.707: g_dbus_proxy_get_object_path: assertion 'G_IS_DBUS_PROXY (proxy)' failed

Log from the startup to the first few occurrences: https://hastebin.com/jabexarebe.yaml
These lines get continuously printed, as of writing the current session error log is about 220k lines long.

Steps to reproduce

I have not a single clue.

Expected behaviour

Not getting these error logs.

Other information

I recently updated to Linux Mint 21 from a 20.3 installation.
I can't tell though if this issue was already present on 20.3 as I only really noticed it during examination of linuxmint/cinnamon#11086.

Please run:

killall csd-power
killall csd-power (it auto-restarts)
.. until you get 'csd-power: no process found'

Then,

csd-power --verbose

Paste the output from that (up to where it starts spitting out those warnings).

Thanks.

This is what it prints (then it loops): https://hastebin.com/wasakafovi.yaml

[mtwebster]

Can you also paste the output to:

ps auxf

[Siphalor]

While trying to reduce the amount of running programs for ps, I noticed that after exiting Steam the logs abruptly stopped.
After starting Steam again, they started again - so there's clearly a correlation.

Anyway, here's the process list with steam running: https://paste.siphalor.de/?a285c4e61535ae46#BZsVAsvdgjibyHd69JbddppMNChereUCDqwEWxE8cV7L

Ok, I might have found the actual correlation:

Whenever power management is inhibited, this bug begins to occur.
Since Steam just generally inhibits power management, it also causes this bug while it's running.

I still think that this bug actually sits deeper than cinnamon-settings-daemon and these are just the symptoms.

---

Edit:‌ While I was pretty confident about this guess, the logs just proved me wrong - apparently it also happens when power management is not inhibited.
I think I got tricked by some noise in the data and the fact that refreshing seems to be a lot slower if power management is not inhibited.

[Siphalor]

Hey, I just want to come back to this to share the current state:

I'm still experiencing these issues.
Without Steam running, this gets logged occasionally (I‌ think every few minutes a single line).
As soon as I‌ start Steam the rate increases to 2 lines per second and only slows down after stopping it again.

I don't really think anymore, that power management is involved in this too much.
This seems to happen generally, Steam is the only correlation I can make out.
