Looks like https://bugzilla.gnome.org/show_bug.cgi?id=662113 to me.

What would be helpful would be to test this with the latest
NetworkManager, from git head. You'll need libnl3 3.2.3 for that,
which is not yet in Ubuntu (or to patch the configure.ac file to avoid
blocking the build for that). There's preliminary packages for libnl3
3.2.3 in the daily builds PPA for NetworkManager for Ubuntu:
http://launchpad.net/~network-manager/+archive/trunk. You may want to
test this, which also includes a very recent snapshot from git (from
the 10th of December). The problem is, these packages are largely
untested, so no garantees that anything is fixed, or that it doesn't
break your system. This is further complicated by the fact that
reverting from libnl3 3.2.3 might not be all that easy, but it's
definitely possible.

I'm updating the Ubuntu bug report now to add a procedure for testing.
