Indeed.  Before m-a the messages were very infrequent, one could
consider this a less than serious issue.

After m-a such messages are now frequently encountered when
performing any non-trivial action.

Getting noticeably more garbage on the screen is a problem.

Have you been using the in-development version and noticed less
errors, or is this just speculation?

If you have been using that version, then this is useful information.
Obviously I can know what is happening on my system which is only
a small m-a chroot for the moment--not the most extensive
test setup.

[The standard C-l works in aptitude to refresh the screen.]

The underlying problem is that these internal debug messages
should not be dumped to stdout while using the curses interface.
They should either direct to a file by default or be captured
using apt-pkg/contrib/error.h like other error messages.

  aptitude cannot handle conflicts with multiarch enabled

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).
