Great! Thank you, Edward! My thoughts exactly.

Title:
  aptitude cannot handle conflicts with multiarch enabled

Status in aptitude:
  Fix Released
Status in “aptitude” package in Ubuntu:
  Triaged
Status in “aptitude” source package in Oneiric:
  Triaged
Status in “aptitude” source package in Precise:
  Triaged
Status in Baltix GNU/Linux:
  Invalid
Status in “aptitude” package in Debian:
  Fix Released

Bug description:
  TEST CASE:
  1. Enable multiarch (should be automatic on new oneiric systems)
  2. Install an i386 package on amd64 (like flashplugin-installer:i386)
  3. Mark something with a lot of dependencies for installation
  4. On the confirmation screen, try to remove on of the dependencies (aptitude will now fail to perform upgrades when there's a package conflict w/out removing the i386 libs)

  This renders aptitude painful on a multiarch enabled system (default
  in oneiric).
