You can be sure that the basic functionality _is_ working. In fact, it is a safe assumption to make when you start debugging anything: the error is in the code you wrote, and not in the libraries you are using. Only occasionaly, you'll find that the bug actualy _is_ in the library, but that will be the exception and not the rule, especially if it is about basic, tried-and-tested functionality of that library like the signal-slot system in Qt.
