There's a bug in gjs which results in this error/warning frequently appearing in the journal when running GNOME and doing pretty much anything: g_variant_unref: assertion 'value != NULL' failed it doesn't really have any other consequences, but the frequent occurrence of the message in the logs can be annoying and distracting if you're trying to debug something else. So I'm proposing this as a Beta FE (it affects the live environment, so an update can't fully fix it). I've already sent a fix upstream and backported it to Rawhide and F33, and will mark the F33 update as fixing this bug.
