This can still be reproduced with latest GIT and there's a testcase now:
https://git.keema.collabora.co.uk/git/insanity/insanity-gst.git

The stream-switch test with seed=3235044814 reproduces it quite reliably
(without any debug output... with debug output it doesn't happen that often).
Sometimes there are up to 30s of buffers queued somewhere between the demuxer
and the sinks. This seems to be caused by some burst pushes that happen from
the demuxer where 10-20s of data are immediately pushed downstream and
accepted, and also multiple audio streams return GST_FLOW_OK for some time
(although all but one should return GST_FLOW_NOT_LINKED).


Note that this test generates a non-sparse text stream without disconts and a
fixed 25fps framerate.
