A quick workaround for those annoyed by the duplicate icons, is changing /etc/fstab. By default it uses codes starting with "UUID=". If you replace those codes with the appropriate names like /dev/sda1 for the volumes displayed twice, and remount them (sudo umount /media/VolumeName && sudo mount /media/VolumeName), Nautilus should display them correctly. I don't know whether there are any advantages of using UUID though.
