+    if (interface.lastError().type() == QDBusError::ServiceUnknown)
+    {
+      std::cerr << i18n("%1: no application quitted", 
args->arg(0)).toLocal8Bit().data() << std::endl;
+    }

this is a good thing to add imho. i would, however, probably write it 
something like the following 100% untested and uncompiled code:

QDBusInterface interface(service, path);

if (!interface.isValid()) {
    kFatal() << i18n("Application \"%1\" could not be found using service 
\"%2\" and path \"%3\".").arg(args.arg(0), service, path);
}

interface.call("quit");
QDBusError error = interface.lastError();
if (error.type() != QDBusError::NoError) {
    kFatal() << i18n("Quitting application \"%1\" failed. Error reported was:
\n\n     \"%2: %3\"").arg(args.arg(0), error.name(), error.message());
}

return 0;


the kFatal's will quit the app with a non-zero return.. but yeah.. good thing 
to add in any case.
