OK, I understood the problem:

If you want to define the next media to play, you HAVE TO do it during 
the 'about-to-finish' GStreamer signal, which is not run in the main thread.

As Gambas is not multi-threaded, its 'AboutToFinish' event is a delayed 
version of the 'about-to-finish' signal, raised in the main thread.

And apparently, setting the uri outside of the 'about-to-finish' leads 
to unexpected result, and to deadlock on my system.

When I say that GStreamer is an huge sensitive beast... :-/

Now I will try to find a workaround.
