Error when running trezor-agent due to protobuf and keepkey

[Bunjin]

On debian: Kubuntu 16.0.4
protobuf 3.2

I ran into the following issue

Traceback (most recent call last):

    return _message.default_pool.AddSerializedFile(serialized_pb)
TypeError: Couldn't build proto file into descriptor pool!
Invalid proto descriptor for file "types.proto":
  types.proto: A file with this name is already in the pool.

I solved it by removing any use and reference to the keepkey lib
