Comment 4 for bug 1346541

Note, for the music, documents, gallery etc being imported into the apps (causing duplicates).

That portion of this bug feels related to bug 1413821, which describes that the file manager should use the UriHandler instead of content-hub for files that exist inside ~/Documents ~/Music ~/Pictures /media/*/*/Documents /media/*/*/Music /media/*/*/Pictures etc so then the apps do not import them twice but instead just open/play the media.
