Without x11-themes/gnome-icon-theme-symbolic a lot of the button icons are not shown in recent totem. I've been having this problem for quite a while so I don't know when it stated, but I just now found why. Temporarily unmerge x11-themes/gnome-icon-theme-symbolic to see what ends up missing. Denis.
Added gnome-icon-theme-symbolic dependency to totem, cinnamon, empathy, epiphany, gdm, gnome-bluetooth, gnome-control-center, gnome-documents, gnome-screensaver, gnome-shell, rhythmbox, and yelp. If there is other stuff missing the dependency, please reopen.
