Yeah, the buffer pool messages are harmless and expected. It's the "unable to find tags file" (or whatever it says) that signals the time to revert to v3a3 to rebuild the database after uploading new tunes.

But I really do like the sound quality in v3, and the player has been pretty rock solid so far, apart from the database thing. My guess is that the rebuild code accidently got omitted because of all of the included Karma fixes -- karma doesn't do database rebuilds from scratch normally.

Cheers
