Yes, I got the same result.
I condensed the code to the following
code:

    from base64 import b64decode
    from numpy import loads
    from scipy.linalg import eig

    Abin='gAJjbnVtcHkuY29yZS5tdWx0aWFycmF5Cl9yZWNv'\
    'bnN0cnVjdApxAWNudW1weQpuZGFycmF5CnECSwCF'\
    'VQFih1JxAyhLAUsQhWNudW1weQpkdHlwZQpxBFUC'\
    'ZjhLAEsBh1JxBShLA1UBPE5OTkr/////Sv////9L'\
    'AHRiiVWAAAAAAAAA8D8AAAAAAAAAAAAAAAAAAAAA'\
    'AAAAAAAAAAAAAAAAAAAAAAAAAAAAAPA/AAAAAAAA'\
    'AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA4juM4'\
    'juMYwAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA'\
    'AAAAAACAOI7jOI7jGMB0Yi4='


    Bbin='gAJjbnVtcHkuY29yZS5tdWx0aWFycmF5Cl9yZWNv'\
    'bnN0cnVjdApxAWNudW1weQpuZGFycmF5CnECSwCF'\
    'VQFih1JxAyhLAUsQhWNudW1weQpkdHlwZQpxBFUC'\
    'ZjhLAEsBh1JxBShLA1UBPE5OTkr/////Sv////9L'\
    'AHRiiVWAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAPA/'\
    'AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA'\
    'AAAAAAAAAADwPwAAAAAAAPA/AAAAAAAAAAAAAAAA'\
    'AAAAAKuqqqqqqgrAAAAAAAAAAAAAAAAAAADwP6uq'\
    'qqqqqgpAAAAAAAAAAAB0Yi4='

    A= loads(b64decode(Abin)).reshape(4,4)
    B= loads(b64decode(Bbin)).reshape(4,4)

    print A
    print
    print B

    print eig(A,B)

numpy is 1.0.4
scipy is 0.6.0

Greetings, Uwe
