bug#23900: 25.0.95; GLib-GIO-CRITICAL g_setting-Schema_source_lookup assertion failed on startup

[Markus Triska]

When I do:

   $ emacs -Q

then the following is displayed on the terminal before anything else happens:

   (process:94387): GLib-GIO-CRITICAL **: g_settings_schema_source_lookup: assertion 'source != NULL' failed

Immediately after this, a frame is shown and I can interact with Emacs.

All the best,
Markus

(This bug report unfortunately got no response at the time.)

I remember seeing those messages quite a bit in the past, but can't
recall seeing them lately.  Are you still seeing this problem in more
recent Emacs versions?

With GNU Emacs 27.0.50, I now get different output:

    $ emacs -Q
    Warning: locale not supported by Xlib, locale set to C
    Fontconfig warning: ignoring UTF-8: not a valid region tag

All the best,
Markus

What does 'locale' output?

It says:

    $ locale
    LANG=
    LC_COLLATE="C"
    LC_CTYPE="UTF-8"
    LC_MESSAGES="C"
    LC_MONETARY="C"
    LC_NUMERIC="C"
    LC_TIME="C"
    LC_ALL=

I don't think that's a valid locale name?  With it, I get a similar
error message to you.

$ LC_CTYPE=UTF-8 ./src/emacs

(process:3691062): Gtk-WARNING **: 00:10:05.068: Locale not supported by C library.
	Using the fallback 'C' locale.
Fontconfig warning: ignoring UTF-8: not a valid region tag

So I don't think this is an Emacs problem, and since the original issue
has gone away, I'm closing this bug report.

OK, so the original reported bug, seems to be gone, I guess?

But this new message sounds like you have a locale that's unsupported by
the OS.

And these aren't Emacs messages, are they?  The second one definitely
isn't, but what about the first one?  (FWIW, I didn't find such text
in Emacs, did I miss something?)
