If you see this text, apparently the error that was described here does not occur in this setup.
To see how my server is configured, you can use Firefox with Firebug, or any HTTP sniffer tool (like Wireshark). But it's easier if I just tell you: the page is served as text/html and that's it.
Loading this page locally from disk works for me, but it depends a bit how your file extensions are configured.
