I believe this was fixed in 2.5  The following worked in 2.5 but 
2.4 rejected it:

   # saved as testr.py
   from cStringIO import StringIO
   from csv import DictReader

   data = StringIO(
     'one,"two two",three\n'
     '"1a\r1b","2a\n2b","3a\r\n3b"\n'
     '"1x\r1y","2x\n2y","3x\r\n3y"\n'
     )

   data.reset()
   dr = DictReader(data)
   for row in dr:
     for k,v in row.iteritems():
       print '%r ==> %r' % (k,v)


tim at rubbish:~/tmp$ python2.5 testr.py
'two two' ==> '2a\n2b'
'three' ==> '3a\r\n3b'
'one' ==> '1a\r1b'
'two two' ==> '2x\n2y'
'three' ==> '3x\r\n3y'
'one' ==> '1x\r1y'
tim at rubbish:~/tmp$ python2.4 testr.py

     row = self.reader.next()
