QScrollArea (kinetic scrolling?) eating double click events for inner widgets

In the attached sample app, our Label widget will not receive double click events (no debug message printed to stdout). I'm guessing that the event is "eaten" by the QScrollArea because of kinetic scrolling. Altering the main function to just do

Label label;
label.setText("Double-click me!");
label.show();

does record the double clicks correctly.
