Any chance you can run NM with --log-level=debug and see what (if any)
additional messages are printed out to make sure NM is doing the right
thing?  You can also run:

dbus-monitor "type='signal',sender='org.freedesktop.NetworkManager',interface='org.freedesktop.NetworkManager'"

and watch for the DeviceRemoved signal, which can help us isolate
whether the problem is with NM or libnm-glib/NMClient.
