IIRC, that error was seen when connecting to Riak 0.14.0. What version of Riak are you connecting to?
I might also suggest using the current, unreleased Python client from the master branch on GitHub. It has much better support for threads and persistent connections. Just don't use variant client_id values and PB connections (switch to Riak 1.1 and ignore client_id). One Client can be shared across threads, but not Objects. I don't recall whether Buckets can be shared.
