I think your groups.prefs is corrupted (in /var/lib/squeezeboxserver/prefs/plugin). You should stop LMS, delete it and restart. As said in other post, removing plugin does not remove prefs files
But you probably still should check whether that $master is defined on that line, if only to not have the web UI hang.
