[Gtkpod-questions] Added one song, now iPod says "0 Songs"

[Grant E. <gra...@gm...>]

I used a recent git snapshot to try to add some songs to an A1320
Nano, and it was a bit of a disaster. I followed the instructions,
including creating a backup copy of iTunesDB.

Then I attempted to add an mp3 file.  The mp3 file got copied to the
Nano.  After syncing, the Nano now says there are 0 songs.

I looked around in /mnt/ipod/iPod_Control/iTunes, and apparently the
iTunesDB file I backed per the documentation up is 1) empty, and 2)
_not_used_ for anything. The file that _appears_ to matter is called
iTunesCDB.  There's a backup copy of that in ~/.gtkpod, but it's
identical to the file on the Nano, so that isn't very useful: it's the
same broken iTunesCDB file that gtkpod wrote to the Nano.

All of the original Music files are still there in
/mnt/ipod/iPod_Control/Music/fNN.

How do I get the Nano to recognize them again?
