That is an excellent question. I also don't see why it should not work.
Anyway do you know that there are more debug outputs available as the -v
switch? It is like Chuk Crisler-2 said: add the --gst-debug switches. So for
example:

   gst-launch shmsrc socket-path=/tmp/shm-stream.sock \
     ! "application/x-rtp, sampling=(string)YCbCr-4:2:2, width=(string)720,
height=(string)480, payload=(int)96" \
     ! rtpvrawdepay \
     ! ffenc_mpeg4 \
     ! fakesink --gst-debug=shmsrc:5,rtpvrawdepay:5,ffenc_mpeg4:5,fakesink:5

If you tried those already, what do they say? 
btw: I would like a qualified answer of this issue also :)
