Actually I couldn't believe that this is a real bug, because SUPER+D was working for me since natty alpha ? (can't remember which release it was).
I have a fresh install of natty desktop (64bit). And right now SUPER+D is not working anymore. At least not for all windows.
Open applications: Firefox, Evolution, Nautilus and vdr-sxfe (xine). Only vdr-sxfe window is minimized and maximized when pressing SUPER+D. All other windows don't care about SUPER+D.

Hope that information helps.
