There not really broken, there just not the same thing (-;
Really, there perceived brokeness stems from the fact that 
they pick up the files of the rpm as they are on the system 
at that time.  This is more a philisophical thing in that the 
idea is that when you rollback to this "repackaged" package
you go back to exactly the way your system was at the time the
of the upgrade, such that a rollback really does resemble the 
inverse function of an rpm upgrade/install/erase.  The perceived
brokeness, comes from the fact that the header in the repackaged
package is exactly the same header that was...on your system 
at the time of the upgrade (a common theme) so you end up with
possibly (nay likely) incorrect digests in the repackaged package, but
when you rollback you get the exact same header that was...on your
system at the time you did the upgrade.

So its not a broken package, its not a regular rpm package at all,
its a repackaged package (-;
