I figured out why the guest session doesn't have icons. I noticed in the Configuration Editor that I have "desktop/gnome/interface/menu_items_have_icons" set to "true", but in the guest session this is set to "false". Even when I set this to "true" in the guest session, it still doesn't show any icons.
