Earlier you wrote:

"I am not really sure how to deal with the Introspect message. I am
guessing the receiving C++ application is suppose to respond to this
message by sending back an XML description of its supported interface
(which it shouldn't have any)."

That sounded like the C++ application wouldn't be sending any signals.
If the C++ application is sending signals, it needs to export objects to
D-Bus, which means that it will have an interface, which in turn should
be introspectable. So, you need to handle the Introspect message in the
C++ application, because the Python bindings depend on that
functionality.
