x11-themes/gnome-icon-theme is deprecated for years in favor of x11-themes/adwaita-icon-theme, the problem is that I cannot provide a fix for this as it seems we are the only major distribution still shipping it and, also, upstream looks dead since 2003... hence, it's difficult that a fix from there will come :/
GMAMEUI is a newer fork but even that's kinda dead. See bug #213622. http://gmameui.sourceforge.net/
