eventually the site stopped loading (15+ min) and gave this error:

For me the page loads quickly... and gives the XML parse error.  Which is a page bug: it's sending not-well-formed XHTML as application/xhtml+xml.  If I replace "Minefield" with "Firefox" in the UA string (but change nothing else) then the site sends the same data as text/html, which works fine, of course.

I recommend contacting the site and complaining about their broken output (and equally broken browser-sniffing).
