Need to REMOVE an interface from a superclass.

[Olivier Crête]

Hi,

This is a problem related to the  translation between the C and Python
bindings. It's a separate interface in C. So you can either force
Python to access g_object_set instead of gst_child_proxy_set .. 

Or maybe you can re-implement GstChildProxy in the subclass in a
version that does nothing.
