As the content type is not "text/html", the page template
assumes it has XML content.
"expat" is an XML parser. It is not installed by default
(at least with Python 2.1.x).

Someone else already suggested to use a Python Script (a very
good suggestion!).

An alternative would be to keep the "text/html" content type
and set it explicitely in the template:

    <tal:dummy define="dummy python:request.RESPONSE.setHeader('Content-Type','audio/x-pn-realaudio')"/>


When I remember right, there was a bug in "PageTemplate" which let
the above code fail (not set the header) in some circumstances
(I will probably work in your case).
