QBluetoothDeviceDiscoveryAgentPrivate missing parent

Creating an instance of QBluetoothDeviceDiscoveryAgent on a thread other than the main Qt thread causes this warning:

QObject: Cannot create children for a parent that is in a different thread
(Parent is QBluetoothDeviceDiscoveryAgentPrivate, parent's thread is QThread(0x...) ... )

The QBluetoothDeviceDiscoveryAgentPrivate is an unparented QObject and isn't being moved with its parent to a new thread.

Do you know if parenting QBluetoothDeviceDiscoveryAgentPrivate to QBluetoothDeviceDiscoveryAgent would fix this?
