This isn't a NetworkManager bug; reassigning to gnome-control-center/unity-control-center.

Looks like (at quick glance, without digging into the code) the switch is triggering the wrong thing in NM, rather than disabling wired it's doing something else.

This bug was fixed in the package unity-control-center - 14.10.0+14.10.20140922-0ubuntu1
