Biggest problem is that it has broken ABI in the .so without changing
the .so version. So the automatically ELF library dependancies added
by RPM don't protect you during update.

Before upgrade:

  # rpm -q PackageKit-libs
  PackageKit-libs-0.1.12-13.20080522.fc9.x86_64
  # rpm -q --provides PackageKit-libs | grep libpackage
  libpackagekit.so.3()(64bit)  

After the upgrade

  # rpm -q PackageKit-libs
  PackageKit-libs-0.2.3-2.fc9.x86_64
  # rpm -q --provides PackageKit-libs | grep libpackage
  libpackagekit.so.3()(64bit)

Same soname version, different ABI :-(  

And since gnome-packagekit versioning is done on the soname:

  # rpm -q --requires gnome-packagekit | grep libpackage
  libpackagekit.so.3()(64bit)  

You can update PackageKit-libs without updating gnome-packagekit 
and get a broken install due to the ABI change:

  # gpk-application 
  gpk-application: symbol lookup error: gpk-application: undefined symbol: pk_enum_list_new

So if you want to push this to F9 you'll need to make sure that the
new PackageKit-libs RPM, has a Conflicts: gnome-packagekit < 0.2.3-3.fc9
or re-spin the upstream release to increment the .soname version
