Xubuntu sets XDG_DATA_DIRS, and then places it's system wide configs
appropriately. Since XDG_DATA_DIRS isn't set, Thunar looks for the
files in the standard XDG locations, where there are no defaults. This
is as per the XDG spec.
What Thunar's behavior is at this point, I'm not sure, but my guess is
it casts about for the first .desktop file is can find that supports
the MIME type. That's why Emacs opens up

Yes, but you shouldn't. That only fixes Thunar - all the other Xubuntu
customized packages that use XDG won't be able to find their
I'm not sure where Xubuntu sets XDG* but you said this was an LTSP
customized setup? You've probably changed how the X login process
works, replacing the chunk of xinit that sets the vars to what Xubuntu
On my Xubuntu system XDG_DATA_DIRS is set to:
Set up the environment to match that at login and you should be golden.
