I've been using Rhythmbox(v 2.96) to copy podcasts to my IPod Classic 120GB. This works, but some time after I upgraded to Ubuntu 12.04, I found that every time I copy a new podcast to the IPod, all of the old episodes of the podcast on the IPod get a duplicate entry. This happens every time, so after a while, I get dozens of copies of each podcast episode.

The duplicates only appear on the IPod itself and not in Rhythmbox's view of the IPod. ITunes does see the duplicates, however.

Has any one else encountered this?
