For the rtsp part of bug #539548, yes, this is the same. 

Actually, rtsp creates 2 udpsrc.
The first one is bound anonymous (port 0) for RTP.
The second one for RTCP is bound on port + 1.

The port is retrieved from udpsrc0 property port. 
As it is not set properly on anonymous binding, udpsrc0->port is still 0.

GST_DEBUG=udpsrc:4 gst-launch udpsrc port=0
says "bound, on port 0"

Then, RTCP port is 1 and trying to bind a socket on port 1 is only allowed for
root !
So rtsp element will fail for any non root user.

There is just a getsockname to do after the anonymous binding in udpsrc to fix
it.
