(FWIW, John didn't claim the error is in the postprocessing at your
site, Aleksey. He only said the symptoms become visible there)

I think, for John as for other developers, the term "postprocessing"
includes everything that is run after the actual tests were run.
Especially, this includes creating XML and collecting the XML results.

Technically, creating the XML is part of the build system and collecting
the results is part of local postprocessing at the testers' sites.

Obviously, one of those two steps went wrong, since the old-style
results look correct.

I have deleted a couple of test results which looked outdated for
various reasons. So, the symptoms should go away for now. However, the
cause stays unknown (and I currently don't have enough time to
investigate this thoroughly).

In the course of this cleanup, I also found out that several tests were
moved, again without notifying the testers. I will stop complaining
about this since the complaints apparently didn't help at all. Please,
understand that I'm unable to sort these things out every day.
