JPEG file that is not decoded by jpegdec

This JPEG file contains 0xff 0xff 0xd9 at the end.  jpegdec fails to identify
this as an end marker.

Test with
gst-launch -v --gst-debug=jpegdec:5 filesrc location=sony.jpeg blocksize=32000
! jpegdec ! fakesink

(blocksize is set to avoid getting lots of debug output before the full frame
is read).

Test output:
