Another crash while running xauth brute force mode

[Deleted user]

I'm seeing another crash in the xauth brute force mode.

Traceback (most recent call last):
File "ikeforce.py", line 2582, in
mcfgIP = str(dicCrypto["MCFG_IPi"]).decode('hex')
KeyError: 'MCFG_IPi'

Not sure what would be needed to track this down.
