Wrong component executed on Loader

We are creating two different components via Qt.createQmlObject, then assign one of them to a loader and the code executed is 50% of the times the one of the other component.

I.e. running the attached program i get "COMPONENT1" in the terminal about 50% of the times.

Can only reproduce on armhf (i.e. the Ubuntu Phone) if running on regular Linux it works fine

The problem disappears if the third parameter to createQmlObject is either different or non existant.
