device.py

Have all dependencies installed. Can load a factory image with .adbtool.py -a "path/to/fw.zip"
Afterwards, using "-l" shows:
INFO: Welcome to abootool by Aleph Research, HCL technologies
INFO: BY OEM:
INFO: -------
INFO: motorola: 2
INFO:
INFO: BY DEVICE:
INFO: ----------
INFO: SHAMU: 1 harpia: 1

Now, when I run ./abootool.py alone after loading firmware, i get:

INFO: Welcome to abootool by Aleph Research, HCL technologies
INFO: fastboot connected to ZX1G22K2HQ

TypeError: __init__() takes exactly 1 argument (2 given)

Have looked through the code, but cannot figure out what's failling.. __init__ in device.py??
