Yes, yes, this is clear to me. But only after you have already explained
this in your previous email ;)

OK. Agreed. Lets wait for the "real" bug report.

FYI. I am still investigating that redhat internal bug report. And yes,
it was the real application. But. I still think that it fails by another
reason, just the test-case they provided doesn't match the reality and
it hits another (this) problem by accident.
