Thanks for the bug report. I'm in the middle of moving house so here's just a 
quick 
idea.

The detection of duplicates (for non-converted and non-podcast items) is based 
soly
on the attributes "title", "bitrate", "time",  and "filesize".
Are you absolutely sure that you are adding the same file again? Not a 
differently 
encoded version of it. Or one from a single where the sound engineer left a 
couple more 
seconds of silence at the endi than at the album version?
Even changing id3 tags can often lead to a change in filesize and thus make it 
look like a different song.

Try this to find the actual difference:
$ grep "No Sin" $IPOD_MOUNTPOINT/iPod_Control/.gnupod/GNUtunesDB.xml | less -S
