    As you say yourself, what someone _think_ is not a useful argument.

That is true, but you are the one that has to convince me, not vice
versa.

It seems that you and I define "serious" in a different way.  My
criterion says that a bug where an important feature does something
that is indisputably wrong and that causes real trouble is a serious
bug.
