For some reason you have two InnerBlock classes in your code. A
demonstration:
>>> class A(object):
... def __init__(self): pass
...
>>> class B(A):
... def __init__(self):
... A.__init__(self)
...
>>> B()
<__main__.B object at 0x2b67aae02c90>
>>> class A(object):
... def __init__(self): pass
...
>>> B()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 3, in __init__
TypeError: unbound method __init__() must be called with A instance as first
argument (got B instance instead)
Are you perhaps importing your main script into your main script?
