[Nowhere man]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; rv:1.7.3) Gecko/20041026 Firefox/0.10.1 (Debian package  0.10.1+1.0PR-4)
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; rv:1.7.3) Gecko/20041026 Firefox/0.10.1 (Debian package  0.10.1+1.0PR-4)

In an XHTML document, a relative URI should be appended the in-scope xml:base to
resolve an absolute URIRef, but Firefox doesn't.

Reproducible: Always
Steps to Reproduce:
1. Go to the given URI
2. Follow an hyperlink

Actual Results:  
Firefox tries a bogus URI based on the document URI.

Expected Results:  
Firefox should resolve URI by appending the href attributes to the given xml:base.

Changing title, as xml:base only applies to XHTML 2.0 (see
<http://www.w3.org/TR/xhtml2/mod-hyperAttributes.html#adef_hyperAttributes_xml:base>)

Actually, I think you'll find that Firefox (and Seamonkey, since Firefox doesn't
have its own XML parser) does support xml:base in XHTML 1.0, assuming it's XML:
your URL is being served as text/html, so it's being interpreted as a strange
and somewhat invalid form of HTML, not XHTML. Change to application/xhtml+xml,
and you'll find that XHTML 2.0 (which is, after all, still a Working Draft)
isn't exactly supported beyond XML pretty-printing just yet, change to XHTML 1.0
and you'll find that you've forgotten to add an xml:base attribute anywhere, add
that, and you should see that it works.
