The easiest way is to grab transmageddon from git master and just put together a mpeg ts transcode. It is a segmentation fault.

(transmageddon.py:24104): GStreamer-CRITICAL **: gst_value_list_get_value: assertion 'index < VALUE_LIST_SIZE (value)' failed
Segmentation fault (core dumped)

Ok, found a simple test case:
gst-launch-1.0 filesrc location="A_Digital_Media_Primer_For_Geeks-360p.ogv" ! decodebin ! deinterlace ! mpeg2enc ! mpegpsmux ! filesink location="/tmp/test.mpg"

It seems the deinterlace plugin is to blame, pipeline runs fine withot it.

This fixes the crash, but it still doesn't work:

Works with an additional videorate before the encoder. In any case, the crash is fixed.

Should also be picked into 1.2 probably
