What Python release are you using?  With Python 2.5, your code gives me
instead:

>>> a.test
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "a.py", line 11, in __call__
    return self.func(self.instance, *args, **kwds)
TypeError: __getattr__() takes exactly 2 arguments (3 given)
>>> 

so there would seem to be some "mis-alignment" wrt the problems you
observe...
