Comment 14 for bug 1065380

For an interm workaround, install blueman and disable gnome-bluetooth running at startup.

blueman has controls to select the bluetooth profile for a connected device by hand.

This means you will have to be near your computer in order to enable your bluetooth headset.

I am not sure they are intended to affect this bug, although they might.

Has anyone tried "Disable = Socket" ?
