Thanks. Using QDBusConnection did it. Using this signature (QString,bool,QVariantMap) with my dbus interface does not work though.

My struct (FSOResourceStatus) was defined as QString,bool,Map<QVariant> but did not work.

Nevertheless, using only a connection and no struct but Qt datatypes directly as you stated above does the job. But it still makes me wonder why it does not work with a QDBusInterface...
