Re: message used serializer that is not accepted: 4

Hello Irmen,

It comes when I try to send a class from my client to a server (all running
locally now):


The output from the server is:

Object <__main__.csoundServer instance at 0x103e986c8>:
    uri = PYRO:obj_16dcb9d52bf7406a81becb3954bd11a1-wgdsaCLVfRM@public.gmane.org:56711
    name = example.cserv
Pyro daemon running.
Exception in thread Pyro-Worker-4355059472 :

"+classname)
ProtocolError: unsupported serialized class: instr0


And the output from the client:

WatchGuard Dimension instantly turns raw network data into actionable 
security intelligence. It gives you real-time visual feedback on key
security issues and trends.  Skip the complicated setup - simply import
a virtual appliance and go from zero to informed in seconds.
