potato's apt makes the wrong decisions on dist-upgrade
There've been quite a few people coming to the debian-user list recently
with the problem that packages like man-db and xbase-clients go missing
when upgrading from potato to woody using 'apt-get dist-upgrade' with
potato's apt. I had been advising people to upgrade dpkg and apt to the
versions in woody first, which does seem to fix those problems, but at
the cost of removing other packages along the way which the user will
have to reinstall - so it only helps to some extent, and may not be
something we can recommend.
What can we do about this? I think we need to come up with a way to prod
potato's apt into making the right decisions on dist-upgrade. For what
it's worth, I haven't managed to reproduce the man-db problem yet, but I
can reproduce xbase-clients being removed. Here's the 'apt-get -o
Debug::pkgProblemResolver=1 dist-upgrade' output with potato's apt:

I would love to see a similar log of man-db being removed, as I maintain
both it and groff and can probably do something about it if only I can
find out what. If anybody can get something like this, please tell me as
soon as possible.
This was all in a chroot, hence the relatively small amount of stuff
installed. Real systems do seem to have the problem too, though.
