A lot of them are unused and don't follow current guidelines (HIG) and
style. Others are yet available with a fresh look in gnome-icon-theme

Four icons are used by gnome-applets/gnome-panel, but those apps should
use available icons in gnome-icon-theme. Those icons are
      * gnome-mailcheck (by mail check applet) -> should use
        "stock_inbox.png" or "stock_mail*.png"
      * gnome-modem (by modemlights applet) -> should use modem.png
      * gnome-money (by stock ticker applet) -> should use
        stock-ticker.png
      * laucher-program.png (used by panel to add a launcher) -> mmhhh
        no valid icon in g-i-t. Just stock_init.png with a starting
        space shuttle.... or maybe gnome-fs-executable

I'll work on a patch for applets. Any idea about launcher?

So his is redux list of useful icons, IMHO. The (?) means that maybe we
can remove it too.
