bug#31168: 27.0.50; dconf spews warnings on Emacs startup

[Lars Ingebrigtsen]

When I start Emacs, I get several screenfuls of this:

(emacs:22926): dconf-CRITICAL **: unable to create file '/run/user/1000/dconf/user': Permission denied.  dconf will not work properly.

(emacs:22926): dconf-CRITICAL **: unable to create file '/run/user/1000/dconf/user': Permission denied.  dconf will not work properly.

(emacs:22926): dconf-CRITICAL **: unable to create file '/run/user/1000/dconf/user': Permission denied.  dconf will not work properly.

I assume that this means that my Emacs is compiled with settings that
aren't present when I'm running Emacs, but I think Emacs shouldn't be
outputting these messages, either.  "CRITICAL".  (I don't care about
"dconf", whatever that is.)

If it is Emacs that's outputting it, that is, and not some library we
have no way of shutting up?

Is this after "su" by any chance?

If so, this is not specific to Emacs.
See eg explanation at https://bugs.debian.org/772910#15
and https://bugzilla.redhat.com/show_bug.cgi?id=753882

If not after su, then I guess your desktop session didn't initialize
properly, or somesuch.

Hm...  I may have su-d at some point, but this is as my own user, but
you may be onto something:

larsi@corrigan:~$ ls -l /run/user/1000/dconf/user 
-rw------- 1 root root 2 Apr 15 21:36 /run/user/1000/dconf/user

That file is owned by root, so ...  er...  I may have su-d and started
an Emacs before and that left that file behind?

Youʼre running some variant of Debian, so 1000 is your uid, I
assume. Those files are owned by the user with uid 1000 on my debian
box.

That's definitely wrong.

Sounds plausible (and should be easy to test), but in any kind of modern
desktop environment I would expect that file to be created with
appropriate permissions when you first login to a graphical session.
Maybe this was in a ssh login or somesuch though?
Anyway, I don't think it's an Emacs issue, really.
It's certainly not new, eg https://bugzilla.redhat.com/show_bug.cgi?id=921689 .

It could be.

Nope.  So I'm closing this bug report.

Thanks for the help.
