It looks to be related using an entity reference in an xmlns attribute. Our svg
reader that determines the size of an svg doesn't expand the entity, so it
doesn't recognize the starting svg tag as being in the right namespace (from
debug log: SvgHandler::getMetadata: Expected &lt;svg&gt; tag, got svg in NS
&amp;ns_svg; )

This is possibly an upstream issue with whichever xml library we use to read
svgs.

However, didn't we use to assume the image was 200x200 if we couldn't find a
width/height, or something like that(?)
