It could be that the QDBusArgument::currentType() of the map values is not handled in dbusArgumentToVariant(), therfore an null QVariant is returned. Try adding a qDebug() statement in that function to check the reported type:

Code:

QVariant dbusArgumentToVariant(const QDBusArgument &arg) {
    qDebug() << "dbusArgumentToVariant. Current type is" << arg.currentType();
    switch (arg.currentType()) {
    case QDBusArgument::BasicType:
    case QDBusArgument::VariantType:
        return basicTypeToVariant(arg);
    case QDBusArgument::ArrayType:
        return arrayTypeToVariant(arg);
    case QDBusArgument::MapType:
        return mapTypeToVariant(arg);
    default:
        qDebug() << "dbusArgumentToVariant. Type not handled.";
        return QVariant();
    }
}

I would expect the map values to be basic/variant type, so perhaps QDBusArgument::asVariant() is returning a null QVariant.
