#58 scanner duplicate exception w/playlist

[Anonymous]

I'm running the scan of my ~11,000 entry file, and
having problems
when it gets into pre-existing playlists. The main
problem is
that it blows up and stops processing at one point,
with the
following exception in the log:

SEVERE: bus-problem with scanner daemon
Message: db-problem adding tune to playlist
Root cause: Message: sql-problem updating list
Root cause: java.sql.SQLException: Invalid argument
value: Duplicate
entry '55496-48321-6' for key 1

Version 2.5.

Any idea what inconsistency the duplicate check is
complaining about?

thanks,
