Rhythmbox does not see bluetooth device

Pair a device such an Android phone to Ubuntu 12.04 LTS Precise Penguin. The computer and device can then transfer files between them. Go to Rhythmbox and select menu item "Music / Check for New Devices". Notice that the Bluetooth phone does not show up in the list of Devices of Rhythmbox.

People expect to transfer files, particularly their music, between their computer and devices via Bluetooth.
