this is just after a clean apt-get upgrade (well, four iterations or so, until it stopped aborting with 'package a not configured, which package b needs, so i'm taking a hike' style messages) this doesn't look hard to fix, but it's possible that whatever causes this might be happening on all your installs, maybe? or, again, maybe it's just me?
