I' ve removed the duplicate tag and confirmed that the problem still exists under the current update of Karmic.
It appears to be a kernel bug and not related to network-manager. The kernel appears to repeatedly connect and disconnect the device state and this causes the connection to fail immediately or within a few seconds of bringing it up.
