Case 1: A package is install but, now, has been deleted from the development/update tree and the installed package blocks updates. The current answer is to manually remove the package (yum remove or rpm -e) if, and only if, you know that package was deleted .. the recent case of dbus-qt.
This could be worked around with an "obsolete-packages" rpm in the repository, which would mark as Obsolete all such known packages.

Case 2: This is similar to case 1. In this case, an older version of a package is in the development/update tree, The currently installed packages include one or more packages which are a "more recent version" but one that has problems ... therefore, we need to "roll back" the package. Again, this can be handled manually via yum remove/install or using rpm --oldpackage if you know that the situation exists.
In the non-devel tree, this is "solved" with Epochs. In the devel tree, I'd say the best thing to do is watch closely, because you're using the development tree.
