Meanwhile, I also found the fix from October. I can confirm that the
issue occurred on 2.3.11.3 only. I switched to the previous version
(which is pretty easy thanks to Docker) and the issue disappeared. All
messages were indexed properly afterwards.

I applied the fix and will observe it for the next couple of days.
The assertions have been misplaced anyway from my viewpoint because
the asserted fields (or properties or whatever, I don't know how
they're called in C) are not accessed in every case.

I am happy that this is scheduled for 2.3.13. Although, I hope that
the payload_input or payload_output won't be NULL when
payload_finished is true. :)

Thanks a lot to you guys for all the effort. I would not be able
to resolve this on my own without your help.

Best,
Manuel
