Title:
  xml.parsers.expat.xmlparser.UseForeignDTD requests a non-optional
  parameter, conflicts with the documentation

Status in “python2.7” package in Ubuntu:
  In Progress

Bug description:
  I just noticed that while digging a traceback I was getting when
  running lazygal.

  According to python 2.7.3’s documentation
  (http://docs.python.org/library/pyexpat.html#xml.parsers.expat.xmlparser.UseForeignDTD),
  UseForeignDTD takes an optional parameter. However the latest version
  of the interpreter in Quantal chokes when no parameter is given:

      python -c "from xml.parsers import expat;
  parser=expat.ParserCreate('UTF-8'); parser.UseForeignDTD()"

  results in:

      Traceback (most recent call last):
        File "<string>", line 1, in <module>
      TypeError: UseForeignDTD() takes exactly 1 argument (0 given)

  This is a recent regression as I was running lazygal without a problem
  on Quantal a couple of weeks ago.
