Its Qt's way of telling you that you cannot transport QVector<CustomType>
through a QVariant (which is what the data-driven stuff uses behind the
scenes). What you can do is transport a QList<QVariant>, so you'll have to
wrap your objects of CustomType into a QVariant and then put that into a
list. See the QVariant api docs for the necessary steps to make custom
types known to it.
