Version: 2.3-GIT (using KDE 4.4.2)
Installed from: openSUSE RPMs
After move, and deletion of old files, Amarok shows a dialog with: "Could not delete file ." and indeed doesn't remove empty source directories.
the dot may indicate that it's trying to treat a directory as a file.
Ah, it would be great if Amarok would also remove nested directories. Like music/artist/artist2123/artistblahblah is a source directory, and we move it's content to music/%artist/, then if artistblahblah/, artist2123/, and artist/ contain only themselves all those dirs could be removed.
