----- Mensaje original -----
> From: "Daniel P. Berrange" <berrange at redhat.com>
> 
> When running virt-viewer with the --reconnect argument, when
> the session closes, the VirtViewerWindow instances were being
> freed, but not the GtkWindow itself. So the orphaned window
> stayed around doing nothing. The GtkBuilder instance was also
> leaked.
> 
> Fix these two leaks & also add some debugging to help future
> troubleshooting
