Following up on that, apparantly the way we generate the signal registration 
is only working for simple types. The following diff to the vala generated 
code leads at least to the correct signature w/ dbus, so my signal callback 
gets finally called:

 void _dynamic_Test1_connect (gpointer obj, const char * signal_name, 
GCallback handler, gpointer data) {
        dbus_g_object_register_marshaller 
(g_cclosure_user_marshal_VOID__BOXED, G_TYPE_NONE, G_TYPE_HASH_TABLE, 
G_TYPE_INVALID);
-       dbus_g_proxy_add_signal (obj, "Test", G_TYPE_HASH_TABLE, 
G_TYPE_INVALID);
+       dbus_g_proxy_add_signal (obj, "Test", 
dbus_g_type_get_map("GHashTable", G_TYPE_STRING, G_TYPE_VALUE), 
G_TYPE_INVALID);
        dbus_g_proxy_connect_signal (obj, signal_name, handler, data, NULL);

So apparantly we need to use dbus_g_type_get_map for a{sv} [and likewise, I've 
seen dbus_g_type_get_collection getting used for arrays].

How do we move from here?
