Hi, I don't know much about messages and it's queues from the python side, but maybe a hint to the C++ side will help you to continue. It appears that the object you get back is a wrapped shared pointer. So basically a pointer to a gr_message which's C++ interface is documented here: http://gnuradio.org/doc/doxygen/classgr__message.html In C++ you can use the shared pointer like a usual pointer to that class so I guess that's the same in gnuradio. Just try if you can get the length of the message with returned_var.length() Usually with the msg() member you return an unsigned char pointer to the actual data of the message. My best guess would be that this is wrapped to a list of numpy's uint8 values. I hope that makes it possible for you to continue. Another possible source might be the QA code for gr_msg_source and gr_msg_sink (if there is any) which should deal with messages in python.
