Thanks for your patch!

This is fixed in git now and it will be part of the next upload. Your
patch was superhelpful to get to the bottom of the problem, the new
apt binary did not always initialize the depcache/policy in the right
order so that the depcache ended up with the wrong pkgPolicy. This
should be fixed in HEAD and a test was added.
