Hi Graham, I don't think this is a dependency issue. I'm going to back out the changes I made earlier as I pulled the trigger too quickly with those. What would be good to know is what 'buf' is set to in your scenario. Here's a little script that hits the same path your traceback goes down. It runs successfully on xenial-queens for me.
from cryptography.fernet import Fernet, MultiFernet key1 = Fernet(Fernet.generate_key()) key2 = Fernet(Fernet.generate_key()) f = MultiFernet([key1, key2]) token = f.encrypt(b"Secret message!")
