I was seeing the same issue. I also wasn't able to alter my library listing to exclude the duplicate UbuntuOne purchased music, I did, however, find a workaround for now. I did the following:
NOTE: Save you podcast locations as the following may wipe out their locations. 1. Opened Rhythmbox. 2. Went to Edit -> Plugins 3. I disabled the "Ubuntu One" plugin. 4. Went to Edit -> Preferences 5. Changed my library location to only be my main local music folder. 6. Created a symlink to the purchased music folder in my music folder: ln -s ../.ubuntuone/Purchased\ from\ Ubuntu\ One/ ~/Music/UbuntuOne 7. Close Rhythmbox 8. Went into ~/.local/share/rhythmbox 9. Removed the following files: playlists.xml, podcast-timestamp, rhythmdb.xml 10. Logged out of my user. 11. Logged back in. 12. Restarted Rhythmbox. I no longer have duplicates. So was I figure is happening is the following. The "Ubuntu One" plugin has a bug causing it to list purchased music twice. This plugin also prevents you from changing your library location (even through dconf editor). Unfortunately, I haven't found a way to get Rhythmbox to clean up its index onces the duplicates are in there. That is why it is needed to delete those files in step nine. I am guessing none of this will be much of an issue once they fix that plugin. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/934206 Title: track duplication from RB-U1 To manage notifications about this bug go to: https://bugs.launchpad.net/rhythmbox-ubuntuone/+bug/934206/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
