This is likely due to a pickle bug in python 3.1 but I haven't yet tracked down an appropriate ticket on bugs.python.org
Unpickling a Binary object in 3.1 fails:
Python 3.1.5 (default, Jul 9 2012, 22:15:20)
[GCC 4.5.3] on linux2

>>> from bson.binary import Binary
>>> b = Binary(b'123', 2)
>>> p = pickle.dumps(b)

No issues in 3.2:
