I suspect that your problems are caused by the Variant wrapping in the properties
interface. Here's what works for me:

  bus = dbus.SessionBus()
  remote_object = bus.get_object("org.kde.konqueror-6730",

  iface = dbus.Interface(remote_object, "org.freedesktop.DBus.Properties")
  iface.Set('com.trolltech.Qt.QWidget', 'geometry',
            dbus.Array([200,200,200,200], variant_level=1))
No idea why the Set(..., Get()) wouldn't work, probably the variant_level isn't
preserved as one would naïvely expect?
