A symbolic icon isn't anything magical. It's just an SVG with
replaceable colors. If you use St.Icon with a FileIcon, it should just
work, assuming the file exists. All St.IconType.SYMBOLIC will try to
do will be to append '-symbolic' to parts of the icon. We should
probably scrap that code at some point - it was put in so we would
have full-color fallbacks when not all of the symbolic icons were
created yet, and those days are long gone :)
