I can't pull the id3 info from mp3 files using the music database. attached is the configuration.log . it's been doing this since 1.1 beta (haven't used MP in months before that, sorry).
"2009-10-05 18:42:05.304600 [Info.][Config Main]: Musicdatabasereorg: Unhandled error Length cannot be less than zero."
Helmut already fixed this bug (mantis 2497)
