Comment # 10 on bug 1204605 from Johannes Segitz

It is possible as long as the currently loaded policy knows about the types
used to apply the labels. This is not the case here. Loading the policy from
disk is the *problem* here, not the solution.

Either transactional update needs to order this so that this doesn't happen or
rpm needs to use the policy outside the snapshot. 

I'll also bring in the rpm maintainer as I'm not sure which solution we'll
chose.
