Looks like you found a chapter that hasn't been updated since the
GStreamer-0.8 days. You should ignore everything in there, it doesn't
apply any longer. (Please file a bug against the documentation for this,
if there isn't one already)

In GStreamer-0.10 you need to send a NEWSEGMENT event instead. See the
design docs (in the gstreamer core source code under docs/design/) and
the API documentation for gst_event_new_new_segment_full() [1] for more
information.
