> In Python 2.6, importing qpid raises "ValueError: unknown url type: /.../specs/amqp.0-10.dtd"
> File "/usr/lib/python2.6/dist-packages/_xmlplus/sax/expatreader.py", line 109, in parse
> xmlreader.IncrementalParser.parse(self, source)
> File "/usr/lib/python2.6/dist-packages/_xmlplus/sax/xmlreader.py", line 123, in parse

> File "/usr/lib/python2.6/dist-packages/_xmlplus/sax/saxutils.py", line 523, in prepare_input_source
> f = urllib2.urlopen(source.getSystemId())
> File "/usr/lib/python2.6/urllib2.py", line 124, in urlopen
> return _opener.open(url, data, timeout)
> File "/usr/lib/python2.6/urllib2.py", line 381, in open

> File "/usr/lib/python2.6/urllib2.py", line 242, in get_type
> raise ValueError, "unknown url type: %s" % self.__original
> This didn't happen in Python 2.5 (on Ubuntu 8.10 at least). The xml.sax routines use urlopen which cannot handle the filename (at least without a file:// prefix).
> Reversing r656301 fixes this by always prefixing the filename with file:// (not just for Python 2.3). I'm not sure if this would fix it for all releases/versions though.
