QTScript default conversion from Qt Script to C++ fails with objects as properties of objects

calling a C++ function from a script with an object containing object members results in the object member being converted to a QString instead of a QVariantMap as documented and as the embedding object has been converted to.

code snippet (excerpt):

— script —
var obj = { foo1: "bar", foo2:

{ a:1 }

};
globalObject.func(obj);

— c++ —
void MyObject::func(QVariantMap obj) {
qDebug() << obj.value("foo1").toString() << obj.value("foo2").value<QVariantMap>();
}

possible solution: convert the QScriptValue recursively like this:
QVariantMap convertScriptObject(const QScriptValue& object) {
QVariantMap result;

QScriptValueIterator it(object);
if (object.isObject()) {
while (it.hasNext()) {
it.next();
if (it.value().isObject())

{ result.insert(it.name(), convertScriptObject(it.value())); }

else

{ result.insert(it.name(), it.value().toVariant()); }

}
}

return result;
}

OR

fixe QScriptValue.toVariant() for this case
