Have you experienced this error again? Looking at the line in question, it states that the variable traceback is None, but traceback is a module imported at the top of the hub module and the only way I would expect it to be None is if it was accidentally set to None in another module. If you can repeat the error, then let's have a look at it together to find the cause.
