GSreamer and RTCP stream errors

[Fabio Cecamore]

I tried with last version 1.0.7 by sources on a new installation of 
debian 7.0 .
The results is absolutely the same..

root at testingVM:~/code# gst-launch-1.0 rtspsrc 
location=rtsp://192.168.0.253/ch0_0.h264 ! decodebin ! v4l2sink 
device=/dev/video0
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
ERROR: from element 
/GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0/GstUDPSrc:udpsrc3: Internal 
data flow error.
Additional debug info:
gstbasesrc.c(2812): gst_base_src_loop (): 
/GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0/GstUDPSrc:udpsrc3:
streaming task paused, reason not-linked (-1)
Execution ended after 1246241464 ns.
Setting pipeline to PAUSED ...
Setting pipeline to READY ...
Setting pipeline to NULL ...
Freeing pipeline ...

Help please..
