The scan button is disabled while a scan is in progress.

QtDBus is internally used by QtBluetooth. There is no public reference to it in the QtBluetooth context. Please enable logging for the example by uncommenting

//QLoggingCategory::setFilterRules(QStringLiteral("qt.bluetooth* = true"));

in main(). It should provide you with more relevant output. Also, ensure that Bluez has enabled the local Bluetooth device using hciconfig.

I am going to assume you meant Ubuntu 14.04 and Bluez 4.101. The other version combo doesn't make sense to me.  Otherwise please advise. Yes, this version combo does work. Indeed I am using it myself.
