That's right, any time QNAM is used it uses the Qt Bearer backend (unless Qt is configure without bearer). In the case of the network- manager backend, it calls the blocking dbus calls to get list of services, and then for every service to get that services properties. Even for local file:// access, even though the bearer is not even used for local file access, thanks to QNAM private c'tor.
