After a quick look at the code, it seems the algorithm used is quite
simple: it just looks at the metadata in the Banshee database, and
selects tracks which have the same title, duration, artist and are
part of the same album

I think there will be always 2 tracks displayed, so you should only
delete one per group

I think the extension displays the path and filenames (the URI), which
is probably the best way to distinguish the duplicates.
