I have hacked file 'gstrtspsrc.c' from 'good plugins' v.0.10.28 source package
by replacing this line in function 'gst_rtspsrc_create_transports_string':

    //g_string_append (result, ";multicast");
    g_string_append (result, ";multicast;client_port=5000-5001");

Now the camera responds 'OK' on 'SETUP' request but rtspsrc plugin cannot parse
it's respond:

I can provide more info and more tests if it helps us to make rtspsrc plugin
really good.
