"gnome-system-tools just modifies the interface configuration file(s) and runs
ifup immediately on it in this case. I faced myself this problem a few times
some time ago when testing gnome-system-tools/NetworkManager cooperation code,
I found out I could reproduce it through command line too, and that everything
worked as expected if NM wasn't active.
My conclusion was that NM is not releasing properly the interface, so I'm
moving this bug there."
