I used aptitude interactively.  This would be a very serious bug in
it... If you can't see any other way, feel free to reassign this but
to aptitude.  Which already has far too many, unfortunately.  I'd
rather not undo the upgrade, but I've got backups, so I can try
reproducing the situation.  Is there a way to peek at aptitude's plan
before it tries to execute it?
