Please describe the problem:
I used to be able to use the multimedia keys on my keyboard to pause/play skip fwd/back tracks with RB.  These seem to be no longer doing anything in RB.
The keys are still being plumbed in Gnome as can be seen with dbus-monitor:

signal sender=:1.1 -> dest=(null destination) path=/org/gnome/SettingsDaemon; interface=org.gnome.SettingsDaemon; member=MediaPlayerKeyPressed
   string ""
   string "Play"
signal sender=:1.18 -> dest=(null destination) path=/net/sf/gaim/GaimObject; interface=net.sf.gaim.GaimInterface; member=UpdateIdle
signal sender=:1.1 -> dest=(null destination) path=/org/gnome/SettingsDaemon; interface=org.gnome.SettingsDaemon; member=MediaPlayerKeyPressed
   string ""
   string "Previous"
signal sender=:1.1 -> dest=(null destination) path=/org/gnome/SettingsDaemon; interface=org.gnome.SettingsDaemon; member=MediaPlayerKeyPressed
   string ""
   string "Next"

RB just does not seem to be doing anything anymore when I press them.

Steps to reproduce:
1. Obtain a keyboard with multimedia keys
2. Start RB
3. Press keys and watch RB do nothing


Actual results:
Nothing.

Expected results:
Play/Pause and skip FWD/NEXT tracks.

Does this happen every time?
Yes, now.  It used to work just fine.
