Good catch. The same happens when you try to compare
Unicode and a different non-string type:

>>> '1' == None
0
>>> u'1' == None
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
TypeError: expected a character buffer object

The reason is the same in both cases: failing auto-coercion.
I will send a patch for this tomorrow.
