Being in software for over 30 years I assume very little about:
    it's correctness.
But I assume that it could be me, causing pilot-errors.

So what I was trying to say:
Several of the bugs in this range were fixed shortly after the 9.1-release, so the first step I'd like to suggest, is to get beyond this point in the release stream. And test again.

My reasoning was more the other way around: unless you have gone to a release with at least these fixes, you cannot tell whether it is already fixed or not.
Until then, a lot of the debugging could be not fully usefull.
