Why and how do I not allow vlc_object_hold()?
vlc_object_hold() creates a valid reference to a *generic* VLC object; with
that I can at least get, set, register and register variables, crawl the
objects tree, and emit log messages.

It *does* give a valid reference to the object.

That does not make any sense. It works fine now.
