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.

Can you send the python code as a file attachment?

Thanks.

OK, thanks for continuing to look into it!

In case it helps: Below is a Python script + Gstreamer lib where setting the
URL property behaves as expected.  It just toggles between playing two video
clips, setting the URL property when the 'about-to-finish' event fires. Not
sure if this will be of any use, but it might?  I ran this script w/ Ubuntu
16.04 and GStreamer 1.8.2, which is a different system than the one I
originally asked about.  I have confirmed that running Gambas 3.9.0 on the
same system that the Python script below runs doesn't behave as expected.

Thanks again!

I started working on the problem, but just to not be able to reproduce 
yours, but find other ones. At the moment, when I try to change the URL 
property, GStreamer deadlocks, and the program freezes.

Maybe it's gb.media code's fault, but I didn't found what is wrong in it 
yet.

¡¡KISS!! Keep It Simple Stupid!!

The htEdit 1.0.6 version does very tricky things in order to prevent
webview to follow the externals Links. I forgot the wonderfull simplicity
of STOP EVENT sentence... (Here comes the "Stupid" word).
I've Updated to 1.0.7 Version in Gambas's Farm. Much more simple and solid.
Sorry about the noise, GianLuigi.
