Comment 3 for bug 1403214

I've managed to get this somehow working by:

1. adding `or self._args[0] == 'self'` to the problematic condition (hackish)
2. disabling testUnboundMethodsRequiresInstance test (don't know how it works and what exactly is the problem here)

I guess this needs a proper fix, but I have no idea how to do such thing, apparently, it is impossible in Python >= 3.3 :D
