After digging a little bit about that I've realized that QList<QObject *>-typed
Q_PROPERTIES are successfully available for use as QML models even in Qt 5.1.1.

QList<QObject-derived *>-typed Q_PROPERTIES cannot be used as models, since
they aren't automatically converted to a JavaScript array (are rather
kept as QVariant(QList<QUmlProperty*>), for example).

It seems qmlRegisterType<T> requires T be derived from QObject, so
qmlRegister'ing QList<QUmlProperty*> isn't a solution.

Luckily, I'm using QList<QObject *> properties but this'd prevent
things working fine otherwise.

Any hint ?
