gnome hotkeys not working

view story

https://bbs.archlinux.org – I just noticed that the media keys on my keyboard are not working: volume up, volume down, mute,...Also, ctrl+alt+L is not locking my screen.I'm wondering if this is a gnome-settings-daemon issue. g-s-d is running, and working in part because it sets my background, but why are none of these other keys working?Which application actually handles these keys? I've often wondered about the volume keys in particular. Who is drawing the volume bar / mute symbol on the screen? The sound applet? g-s-d?Any ideas?
