#5068: dcinema MXF creation fails

Summary of the bug:
I'm currently fiddling around with h264 based dcinema mxf
For reproduction I uploaded (a working and tested dcinema file)
dcinema-h264.mxf to upload.ffmpeg.org/incoming/
Now I'm trying to create my own video from scratch but I didn't succeed
with encoding my own video file. So I decided to extract the video and
repack it into a new mxf - but this approach failed, too. Am I doing
something wrong or is there an issue with ffmpeg's mxf muxer?
Attached "-report log" file
Regards,
Andreas
----
How to reproduce:
== First - extract h264 from mxf: ==
andreas at notebook:/tmp$ ffmpeg -i dcinema-h264.mxf -vcodec copy video.h264
This works perfectly well and video.h264 is obviously a valid video file
and plays with eg. ffplay
== Second - remux this very same h264 to mxf: ==
