bug#38005: org.gtk.Settings.FileChooser glib schema missing "show-type-column" key

[Josh Holland]

Hi,

I'm using Guix on a foreign distro (Arch), and I have noticed that
Firefox as installed by pacman crashes frequently.  If I run it from a
terminal, I see that the error is the following:

(firefox:1166641): GLib-GIO-ERROR **: 15:05:20.437: Settings schema 
'org.gtk.Settings.FileChooser' does not contain a key named 'show-type-column'

Indeed, with some digging, I find that it is missing from the schema
installed by Guix, although present in the system-installed schema:

$ grep show-type-column 
$GUIX_PROFILE/share/glib-2.0/schemas/org.gtk.Settings.FileChooser.gschema.xml 
|| echo 'not found'
not found
$ grep show-type-column 
/usr/share/glib-2.0/schemas/org.gtk.Settings.FileChooser.gschema.xml
    <key name='show-type-column' type='b'>

If I go chasing down the symlinks to see where the schemas come from, we
see that Guix has installed gtk+ 3.24.10, while the Arch package is
3.24.12:

$ ls -l 
$GUIX_PROFILE/share/glib-2.0/schemas/org.gtk.Settings.FileChooser.gschema.xml
lrwxrwxrwx 2 root root 120 Jan  1  1970

$ pacman -Qi gtk3
Name            : gtk3
Version         : 1:3.24.12+32+g39e28ab933-1
# ...snip...

I'm not sure whether a simple update of the gtk+ package would solve
this, especially as presumably it would trigger a lot of rebuilds.
