You're trying to run md5 over a unicode string, but I'm pretty sure
it's only defined for bytes, and when Python tries to autoconvert the
unicode to bytes (by encoding it in ASCII), this fails because you
particular unicode string contains non-ASCII characters. Basically
make sure to pass md5.new() bytes and not unicode, either by removing
the call to .decode(), or calling .encode() on the unicode object
before passing it to md5.new()

Chris
