This is probably something that searches XDG_DATA_DIRS/something (i.e.
~/.local/share/something:/usr/local/share/something:/usr/share/something
when using defaults, which the greeter will), or some other search path
that includes /usr/local. Possibilities include D-Bus .service files and
gobject-introspection (GIR) bindings.

It's possible that something is also mis-handling EACCES: if searching a
PATH-style path, it should probably be treated like ENOENT, causing /usr
to be tried instead.

Why can't the greeter read files in /usr/local, though? Aren't they
0644/0755?
