Hi,
since [0] streamselector will send a NEWSEGMENT event on the srcpad whenever it
receives a NEWSEGMENT event from any sinkpad. This causes multiple NEWSEGMENTS
in some cases, breaking playback completely (sinks accumulate segments,
timestamps are wrong or better far too early, pipeline stops).

I have a testcase locally (can't share it unfortunately) where it breaks
playback reproducible. Reverting [0] fixes it for me, Wim will investigate how
to fix this properly ;)
