Unhandled TypeError in python wrapper

[gjask]

Sadly I wasn't able to capture response data that caused the error. Also exception returned from fastrpc doesn't seem to contain traceback. So far I know the following exception is raised by calling fastrpc.loads(response_data) and http status code was in range >=200 and <300.

<fastrpc.Fault: -500, Unhandled exception <type 'exceptions.TypeError'>: __init__() argument 3 must be string without null bytes, not str>
