smart_str can't encode a unicde string

[spam@…]

I'm getting

encode() takes at most 2 arguments (3 given)

From line 95 of django/utils/encoding.py :

elif isinstance(s, unicode):

return s.encode(encoding, errors)

I think it should be

elif isinstance(s, unicode):

return s.encode(encoding)

I'm on python 2.5

Cannot reproduce this bug:

>>> from django.utils.encoding import smart_str
>>> smart_str(u'iñtërnâtiônàlizætiøn')
'i\xc3\x83\xc2\xb1t\xc3\x83\xc2\xabrn\xc3\x83\xc2\xa2ti\xc3\x83\xc2\xb4n\xc3\x83\xc2\xa0liz\xc3\x83\xc2\xa6ti\xc3\x83\xc2\xb8n'
