This looks completely garbled today:
It looks broken, both in Firefox 2.0 and lynx 2.8.6 on Linux.
But if you change to language=de or some other language, all is
fine. The sv:Template:GeoTemplate has not changed.
It's a little weird that <h1...>Map sources/GeoHack</h1>
is followed by <html ><head>...</head><body>
(after which the garble begins)
but this is actually the case with the standard GeoHack page.
