Using a CRC to authenticate a message is why we have an SSHv2; SSH made a similar mistake.

Strange that python-crypto would take care of padding for block ciphers and not calculate the CRC for you. I wonder how much code out there assumes it would and become susceptible to accidental corruption of the plaintext.

Great Tutorial! An excellent way to get into Python Crypto Lib.
