Comment 25 for bug 277309

This is still visible in the "Shut Down the Computer" dialogue. This can either be raised by clicking the "Shut Down" option in the System menu (which intuitively enough, completely disappears if you have activated the Fast User Switch panel applet), or by pressing the Power button on a laptop. If you are using a non-Human icon theme, the icon you see next to Suspend is "image-missing" (Tango version at http://en.wikipedia.org/wiki/File:Image-missing.svg ), which sticks out like a sore thumb.

As someone mentioned, Tango icons already exist for suspend and hibernate (see http://git.gnome.org/cgit/gnome-power-manager/tree/data/icons/scalable/actions ). As a highly-visible part of the operating system, this deserves fixing.
