My (limited) understanding of NM is that it expects to manage all
interfaces, and if there's an interface it doesn't manage then that
interface has been disabled for some reason. In any case, the failing
apps (Firefox, Evolution, ...) simply ask NM and believe what it says,
and if NM doesn't manage the interface it's going to say that it's down,
no matter what the reality is.
