Seems like a "This bug was fixed in the package network-manager - 0.9.8.8-0ubuntu7.3" problem.
Same at my place, no proposal repository activated.
My network-manager still is the "old" 0.9.8.8-0ubuntu7.2. So it seems for me like the update of the network-manager did not make it into the "yesterday's patchset", and now we are a bit offline.
So: update the patchset-list to make both changes happen the same time. I think this would solve all the problems with this bug.
