Summary: cgi.py broken with xmlrpclib on Python 2

Initial Comment:
Given a web application which accepts both normal 
HTTP requests and XML-RPC requests, it is 
reasonable for that program to assume it can create a 
cgi.FieldStorage instance in either case. This works 
fine in Python 1.5.2 but causes exceptions in Python 
2.x.x when using the created FieldStorage. This is due 
to the content-type header generated by xmlrpclib.py 
('text/xml') being unrecognised in cgi.py, as a result of 
which no FieldStorage.list is created.

One solution is to reinstate some code in cgi.py from 
the 1.5.2 release, at the end of method __init__, after 
removing the current final two lines:

        #else:
        #    self.read_single()
        # SP 2002/6/15: The following code is taken 
from the Python 1.5.2 version
        # of cgi.py, as incoming xmlrpclib requests 
otherwise do not cause 'list'
        # to be set up correctly.
        elif self.outerboundary:
            # we're in an inner part, but the content-type 
wasn't something we
            # understood.  default to read_single() 
because the resulting
            # FieldStorage won't be a mapping (and 
doesn't need to be).
            self.read_single()
        else:
            # we're in an outer part, but the content-type 
wasn't something we
            # understood.  we still want the resulting 
FieldStorage to be a
            # mapping, so parse it as if it were urlencoded
            self.read_urlencoded()
