Comment 3 for bug 1311389

While I will pursue finding the upstream bug number, I'm not in agreement that this is low priority for Ubuntu clients in a Lts.

Shotwell has no issues with presenting the photos on the mounted volume, Bash along with Nautilus and even Nemo have no issues with the mounted Usb drive.

RhythmBox not only can not see the mounted music it wants to "help" by offering to initialize the entire disk and presenting a dialog that suggests that is the normal thing to do.
