Cleanup plugin definitely does not work with 13.2. I compiled the latest code and I suspect it just not quite right for 13.2. I had many obvious dupes in my library, including files where the directory was non-existant and the plugin never noticed... maybe a quick tweak of the code for that plugin will help it along...
And is everything duplicated? Or is there a pattern to what is?
It was actually only a small % of the library... it turns out that the only pattern I could attribute this to.. the only files duped in this whole sequence were ones recently imported from the rip/ directory.. so perhaps this was a case of the Import Music failing to detect dupes... and then when I moved the whole library and re-imported it, those failures were responsible...
I also notice that upon starting Banshee, it complains it could not find NetworkManager which is correct, I use Wicd... but I was wondering if that will cause problems with Music Sharing once I can get Avahi to work again....
