Internal data flow errors when receiving RTSP stream

Hello all,
I am experiencing internal data flow errors when trying to display
video over RTSP from a Hikvision NVR (specifically it is a
DS-7616NI-SP).
I have tested both playbin and a custom pipeline using rtspsrc !
fakesink (this was in order to discard decoding problems). In both
cases the result is the same: The video is shown briefly (typically
for a second or less..), or not shown at all, then I get an "internal
data flow error" with reason: not-linked and the pipeline is stopped.
I have not seen this before with other IP cameras, so it might be a
problem with the Hikvision NVR. However the same stream works just
fine in VLC -- so it could also be a GStreamer issue.
I am attaching the traces for the playbin test. I am hoping someone
have come through this before. Any pointers on how to debug this
further will be much appreciated.
GStreamer version: 1.2.4.
Pipeline:
gst-launch-1.0 playbin
