SUMMARY

When Samba shares are unmounted (removed), Solid::Device::isDeviceInterface() won't return Solid::DeviceInterface::NetworkShare as type.

STEPS TO REPRODUCE
1. Connect a slot to the signal deviceAdded() and deviceRemoved() of Solid::DeviceNotifier::instance(), respectively.

2. Implement the following code in both slots:

    Solid::Device device(udi);

    if (device.isDeviceInterface(Solid::DeviceInterface::NetworkShare)) {
        qDebug() << "Success";
    } else {
        qDebug() << "Failure";
    }

3. Run the application.

OBSERVED RESULT

When mounting a Samba share, the output will be "Success". When unmounting that share afterwards, the output will always be "Failure".

EXPECTED RESULT

On both occasions "Success" is returned.
