Icons and menus

[Mark McLoughlin]

Hi,
	FWIW, it sounds like it'll be fixed in gtk+ by ignoring icon caches
which aren't accompanied by and index.theme file
(like /usr/share/pixmaps) and by making gtk-update-icon-cache not
generate an icon cache where an index.theme file doesn't exist. See:

	I did a grep in Fedora Core and Fedora Extras devel branches and didn't
find any packages which create an icon cache in /usr/share/pixmaps.

	Looks reasonable, yes. The former is just what all the packages in
Fedora Core do.

Cheers,
Mark.
