Latest ubuntu python client not passing statistics to server

Hi,

We're running the latest current release of the server & Ubuntu python client and the python client is running fine but we're not seeing any statistics in the display part of the server panel. From the documentation it says that layout statistics aren't produced from the python client but media ones are. We're not seeing anything.
I have the collect turned on in the config for the client and queue is set to 10. Am I missing something else?
Thanks
