Please describe the problem:
Since upgrading to the latest Ubuntu Hardy (development version) this morning my multimedia keys are not working to adjust volume nor start/pause/next/prev, etc. in rhythmbox.

Steps to reproduce:
Hardware dependent.  Try to use multimedia keys.

Actual results:
nothing.

Expected results:
rhythmbox responds as expected.  volume control responds as expected.

Does this happen every time?
yes

Other information:
They keys are being pushed up by X.  I can use "ev" to see the events from X.  I can also use the gnome-keybindings-properties tools to assign the mm keys to actions.  It seems they are just not being pushed out from gnome.
