Thanks for your bug report, that's interesting indeed :)
Some quick thoughts:
* I'm sure this is not a problem of the package, the package is not
  doing anything else than having a version, the handling of upgrades
  etc. is handled by apt* and friends.
* I'm not surprised that aptitude offers an upgrade; in my experience
  packages from a mirror have precedence over locally installed
  packages, even if they have the same version.  
* The interesting thing now is why the upgrade doesn't happen; some
  random thoughts: Do you have some pinning in /etc/apt/preferences{,.d/*}?
  Does an aptitude update change anything? Doesn apt-get behave the
  same way as aptitude? What happens if you exchange localhost with
  some "real" mirror?

Maybe someone else has additional ideas.
