0.99.12 (1.fc8) installed in Fedora Core 8.
When I sync the iPod (60GB iPod Video - xA147) any Smart Playlist that is set for Live Updating is empty on the iPod itself. If I resync the iPod with w32 iTunes, it goes back to a state where the playlists display properly on the iPod again. I can also sync it all day long with gtkpod-0.99.8-3.fc6 and they work just fine, but one sync to 0.99.12-1.fc8 stops that. The Smart Playlists DO live update in gtkpod, just not the iPod itself.
It worked in FC8 with version 0.99.11.
