(Just as I suspected :-)

The fix is that piece of code I sent you yesterday (and pushed to
sourceforge), rewriting _untagged_response(<name>) to grab _all_ <name>
responses, repeated below:
def _untagged_response(self, typ, dat, name):
if typ == 'NO':
return typ, dat
data = self._get_untagged_response(name)
if not data:
return typ, [None]
dat = self._get_untagged_response(name)
if not dat:
data += dat
return typ, data
