I've noticed a problem with Amarok. I seems it cannot scan and catalog 
into the database any more than 12607 music files. Does not matter if 
it's with SQLite or MySQL. the progress bar climbs to 13 percent and 
never advances eventually disappears, showing a partial collection list. 
it does stop indexing but there are over 60,000 files in the music 
directory. I can use the files tab and "grab the music directory" and 
drag to playlist, and about 40 mins later all files show up in playlist, 
and they do play and have tag info, but collection tab doesn't show all 
that are in the playlist. Doesn't seem to leave any clue in a log file.  
All files have the same owner:group and attributes.
