Patch 1079734 "Make cgi.py use email instead of rfc822
or mimetools" seems to have broken the cgi.FieldStorage
in cases where the request is a multipart post (for
instance, when a file upload form field is used).
See the attached test program.

With cgi.py revision <1.83 (python 2.4 for instance) I
get the expected results;

374
FieldStorage(None, None, [FieldStorage('param1', None,
'Value of param1'), FieldStorage('param2', None, 'Value
of param2'), FieldStorage('file', '', ''),
FieldStorage(None, None, '')])

but with cgi.py rev 1.83 (current) I get this:

374
FieldStorage(None, None, [FieldStorage('param1', None,
'')])


Another thing that I observed (which isn't reproduced
by this test program) is that cgi.FieldStorage.__init__
never completes when the fp is a socket-file (and the
request is again a multipart post). It worked fine with
the old cgi.py.
