This was fixed by one of these two commits (will be in 1.6.1):

    avcodecmap: Don't allocate dummy codec data anymore, it causes crashes
nowadays

    Multithreaded encoders are going to free this dummy codec data twice, e.g.
    with this pipeline
      gst-launch-1.0 videotestsrc num-buffers=40 ! \
        videoconvert ! avenc_mjpeg ! fakesink

commit e5e78379ad8287cd2b71b4cdb743e905c8cd0369

    avvidenc: Pass the correct user_data to gst_buffer_new_wrapped_full()

    Fixes crash with e.g.

      gst-launch-1.0 videotestsrc num-buffers=40 ! \
        videoconvert ! avenc_huffyuv ! fakesink
