Please describe the problem:
Ghostpads are reported with parent and names attributes only, lacking peer and direction.

Steps to reproduce:
1. gst-launch-0.10 -o foo.xml videotestsrc ! videoscale ! video/x-raw-yuv,width=320,height=240 ! ffmpegcolorspace ! ffenc_mpeg4 ! rtpmp4vpay send-config=true mtu=2048 pt=97 ssrc=123456 timestamp-offset=20619 seqnum-offset=44441 ! identity sync=true !  rtpbin rtcp-support=true localport=9424 destinations=172.16.2.27:9424;

Actual results:
XML representation of the pipeline is missing information on the peers and direction of ghostpads

        <gst:pad>

            <gst:name>sink</gst:name>

        </gst:pad>

Expected results:
The expected result would be something like this:
---8<---------------
        <gst:pad>
          <gst:ghostpad>
            <gst:name>sink</gst:name>
            <gst:parent>rtpbin0</gst:parent>
            <gst:direction>sink</gst:direction>
            <gst:peer>identity0.src</gst:peer>
          </gst:ghostpad>
        </gst:pad>
        <gst:children>
          <gst:element>
----8<----------------------

Does this happen every time?
Yes.
