[Bug 924079] Re: do-release-upgrade fails to upgrade from Oneiric to Precise

Reproduces with 'apt-get dist-upgrade' from a clone of your state.
Debug::pkgPackageManager=true says:

E: Couldn't configure pre-depend libtinfo5 for libncurses5, probably a dependency cycle.

It may be worth noting that this is amd64, and libc6:i386 is being newly
installed here.
