I think we are describing the same problem: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/892454 However, on 11.10 with network-manager 0.9.1.90-0ubuntu5.1 I am not seeing the same problem.
Do you have an 11.10 machine you could test this out on and/or could you pin the older version on the 12.04 install and see what happens?
