Yes, of course, I understand this. I just didn't have time to make one yet,
we've literally discovered the issue only today (well, maybe yesterday,
depending on the time zone).

OK, will do, but, at least superficially, our situation seems very similar =
to
this one, so I thought it would be better to keep this one going. But, agai=
n,
I'll open the new one as soon as I can make a test case for it, if this is =
your
preference.=
