--- Comment #19 from Jeffrey A. Law <law at redhat dot com> --- Note you lost the regression marker when this was made a duplicate of 21161. So it's unlikely anyone would have looked at it until the next release cycle. My understanding from Florian is that at least some of the issues here are regressions, so I've added the marker to 21161.
