Okay, I just tried that one, and it worked.

Today I was trying out gst-rtsp-server/examples/test-netclock and although
I could get it to work, test-netclock-client would die (after emitting a
large number of warnings) with:

 (test-netclock-client:9236): GStreamer-CRITICAL **: gst_mini_object_unref:
assertion 'mini_object != NULL' failed
ERROR: from element
/GstPlayBin:playbin0/GstURIDecodeBin:uridecodebin0/GstRTSPSrc:source/GstUDPSrc:udpsrc0:
Internal data stream error.
Additional debug info:
gstbasesrc.c(2939): gst_base_src_loop ():
/GstPlayBin:playbin0/GstURIDecodeBin:uridecodebin0/GstRTSPSrc:source/GstUDPSrc:udpsrc0:
streaming stopped, reason not-negotiated (-4)
