It is different.  The cause of your issue is probably, that you're
lacking gsettings-desktop-schemas or something similar to it inside
your environment.  Perhaps we could try forming a "gnome-base"
metapackage, that propagates all of dbus, glib, gsettings-schemas etc.
for such purposes (maybe on wip-gnome first)?

I'm sure you know about -E XAUTHORITY by now, but imo we should have a
switch similar to --networking for container operations.  

PPS: Just adding gsettings-desktop-schemas didn't work.  "jami-gnome
glib gnome" obviously works, but that's a little overkill (also it
appears that you'll have to get credentials into this thing, which I
haven't bothered worrying about).
