Thanks for the hint

Well, I actually tested this and the constructor works :)
Without the constructor I get Glib::Object::new() which doesn't use the 
same arguments as HBox::new(). I guess the SUPER call in my constructor 
ends up in Glib::Object because I get a properly blessed object from my 
constructor. I also use INIT_INSTANCE for some bootstrap thingies.
