    In this testcase i follow a different approach than usual: I don't use the full power of
    QtTestTable and QtTestData. This is done deliberately because QtTestData uses a QDataStream
    itself to handle its data. So it would be a bit inapropriate to fully rely on QtTestData in this
    testcase.
    I do use QString in QtTestData because this is thouroughly tested in the selftest.
