Can't decrypt Root Password using lidl_auskey_decode.py

[burgsth]

When I run lidl_auskey_decode.py I'm always getting an error message. I've already tried two different systems

Encoded aus-key as hex string line 1>80000000:       ECBF6766        4674D1E7        06711FE1        C43E49B7

    self._cipher = factory.new(key, *args, **kwargs)
SystemError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats

Both systems running different Ubuntu versions but the result is the same. I also tried to enter KEK and AUSKEY without leading 800000x0 or without blanks. It brings up always the same error.

I've used the version comes with release 1.2 and tried the one on the webpage (v0.2). In v0.3 everything works fine.
