Classic class decoding throws an error

[nick]

import pyamf

class Spam:
    pass

pyamf.register_class(Spam, 'spam.eggs')

x = Spam()
x.foo = 'bar'

bytes = pyamf.encode(x)

print [x for x in pyamf.decode(bytes)]

Using AMF3 encoding, results in:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/nick/projects/pyamf-examples/google_appengine/pyamf/__init__.py", line 849, in decode

Using AMF0 encoding, results in:

Branch is ready for review in r1181

Attached test-248.py returns this on my mac:

[<__main__.Spam instance at 0xbd0dc8>]

Fixed in r1199.
