[pycrypto] _fastmath None !!

[jd]

Hi Guys
    I am serializing the pycrypto keys using pickle.. as suggested in one of recent posts. It is working fine, but giving following problem on cenos 5.1. (stack at the bottom of email)

'NoneType' object has no attribute 'rsa_construct'


    I looked at the code.. it seems while constructing _fastmath is used. Any workarounds / fixes ? I do not think changing to saving tuple would help as it would also need to use __setstate__.. 

Help is greatly appreciated.
Thanks
