Ah, that's interesting.  It means there's probably some environment
variable that gets set and usefor the other things too, or perhaps it
searches relatively to its binary.

Ideally we could patch what it needs in the gdm package definition.  A
second option would be to wrap GDM with the paths such as XDG_DATA_DIRS
it wants.

Thanks, that's the issue I remember seeing.

I'd like to avoid abusing the gnome-shell-assets, so would welcome us
further investigating the sources of GDM to get clues as to what/where
it's looking and what it wants exactly, but otherwise with your
explanation I think this can be a first step (apply this change as is).

Does anyone have a problem with it?
