Comment 3 for bug 1531380

 calling something like this:
    QObject::connect(ns.data(),
                     &NetworkingStatus::statusChanged,
                     this, &QUbuntuEngine::networkStatusChanged);
still does not work.

In networking-status.h, the signal should be declared as:

void statusChanged(NetworkingStatus::Status value);

I looked at the code, and I could not find any tests for the public connectivity-api (network-status.h)
