QBluetoothServiceDiscoveryAgent returns NULL QBluetoothServiceInfo serviceUuid ?

Under Qt 5.4.0 Linux thenBluetooth Scanner Example the QBluetoothServiceDiscoveryAgent always returns QBluetoothServiceInfo serviceUuid value that is NULL for

{00000000-0000-0000-0000-000000000000}

" for any device.

Steps to Reproduce
---------------------------
1 - Buid btscanner example
http://doc.qt.io/qt-5/qtbluetooth-btscanner-example.html
2 - Put breakpoint in service.cpp at ServiceDiscoveryDialog::addService

void ServiceDiscoveryDialog::addService(const QBluetoothServiceInfo &info)
{
if(info.serviceUuid().isNull())

{ qDebug() << "*** NULL service ID"; }

I created another issue in anticipation of the coming Qt 5.5 alpha that reproduces the same behavior on OS X.
