I honestly couldn't tell you why. I hope that's a rhetorical
question. :) Everything under /home/tack/tv is quite straightforward;
there are no symlinks to confuse beacon. :)

Again, hopefully rhetorical. I dunno. :)

That I can tell you. I added a print after the first line
(self._db.query()).

tv|8
|9
buffy|13
Indeed, 9 is empty. Why, I have no idea. But it looks like beacon has
added a phantom parent in there:
/ -> home -> tack -> tv -> (EMPTY) -> buffy
I'll see if I can figure out why when I get home. Unless you have any
ideas. But the directory structure under /home/tack/tv is quite
straightforward, with no symlinks at all.
Ah, but note, if I delete ~/.beacon and run:
BEACON_MONITOR=/home/tack/tv beacon --start
Then the query that before failed now works fine. So there's something
about my having previously attempted to index /data/movies that is
causing this problem. Possibly due to the failure indexing /data/movies
it has left some cruft in the tables that is confusing matters. If so,
aside from the original bug, that's a bug too. :)

I'm sure there are stranger configurations than mine. :)
