Thank you for this. But I'm in doubt whether this works in plugins, too.
It always crahsed.

But I think there is a comparatively more simple solution:

	Somewhere:

		static dissector_handle_t data_channnel_handle;
		data_channnel_handle = create_dissector_handle(...);

	In control channel dissector:

		if ( /* a data channel is announced on port X */ ) {
			dissector_add("udp.port", X, data_channnel_handle);
		}

and also in control channel dissector:

		if ( /* a data channel closing is announced on port X */ ) {
			dissector_delete("udp.port", X, data_channnel_handle);
		}

This works fine.(?)
