Comment 112 for bug 861061

I can't recommend upgrading just yet: the upgrade from ppa:unity-team/staging removes unity completely at the moment. ("unity : Depends: libnux-abiversion-20111213 but it is not installable", even though the libnux-2.0-0 2.0.0~+bzr534ubuntu0+307 package was built only 5 hours ago.)
