I am using vlc as a library, and my main application triggered a X11 error after
I unloaded vlc. So it crashed.

Unless I am missing something, I think I handled this in my patch because I am
testing if the handler has been changed.
Two cases when we close the module :
- The handler is still vlc's one. It means no one unregistered or changed the
handler, so we can register the one there was before.
- The handler is not vlc's one. It means someone changed it, and I leave it as
I don't see any case where it doesn't work. If the handler I restore is not
valid anymore, it is not vlc's responsibility
