ApplicationError Exception Formatting

If I throw an exception in a called function the other host prints the unicode version of ApplicationError, which includes the traceback thrown by the remote function interleaved with newlines. If appears the unicode function on ApplicationError expects the traceback to be a list of lines, but it is receiving a string. (As seen here: https://github.com/crossbario/autobahn-python/blob/master/autobahn/wamp/exception.py#L241) As far as I can tell this originates from https://github.com/twisted/twisted/blob/68d2afa5c2776c242d6bb942813b293b027b837c/src/twisted/python/failure.py#L541

Is there a place I should be overriding this behavior, or is this unintentional? I could really use a guide on error handling with autobahn in general.
