If it helps I looked further into dbus documentation and dbus-1-tqt so the signature for output of GetManagedObjects is a{oa{sa{sv}}} it looks like the first a{ is ignored, but if I ask the reply for it's type it says Map ... from my sample code ... kdDebug() << "reply.front().type() : " << reply.front().typeName() << endl; bool ok = false; TQValueList<TQT_DBusData> list = reply.front().toTQValueList(&ok); if (!ok) kdDebug() << "toTQValueList failed" << endl; else kdDebug() << "toTQValueList worked" << endl; if (!ok) return -1; says reply.front().type() : Map toTQValueList failed I tracked this down to TQT_DBusMarshall::parseSignature() it evidently ignores the first a{ and consequently returns only the last oa{ I think I should file a bug now, but will wait for you to confirm and I will write some code to construct reconstruct TQT_DBusData wih signature a{oa{sa{sv}}}. regards
