On my Debian/Squeeze, this is what I have ended up with.

There should be a way to go directly from *.desktop file to Exec entry.
I haven't figured it out or it is in the works.

Surprisingly, the above sequence fails for ODT files.

I believe xdg-stuff is in it's initial stages and not so reliable at
this moment.
