Hi,

Problem:
- when using GtkBuilder
- embedding a GtkFileChooserWidget in one of the content pages of a GtkAssistant

When the assistant is ran for the second times, the
GtkfileChooserWidget doesn't display at all. Below a sample code
which reproduces the problem :

enum {
	ASSIST_PAGE_INTRO = 0,
	ASSIST_PAGE_FILES_SELECTION,
	ASSIST_PAGE_DONE
};

static void
on_cancel( GtkAssistant *assistant, gpointer user_data )
{
	gtk_widget_hide_all( GTK_WIDGET( assistant ));
	gtk_main_quit();
}

/**
 * Run the assistant.
 */
void
nact_assist_import_run( void )
{
	static GtkBuilder *xml = NULL;
	if( !xml ){
		xml = gtk_builder_new();
		gtk_builder_add_from_file( xml, GLADEDIR "/nautilus-actions-config.ui", NULL );
	}
	GtkAssistant *assistant = GTK_ASSISTANT( gtk_builder_get_object( xml, "ImportAssistant" ));

	GtkWidget *intro = gtk_assistant_get_nth_page( assistant, ASSIST_PAGE_INTRO );
	gtk_assistant_set_page_complete( assistant, intro, TRUE );

	GtkWidget *selector = gtk_assistant_get_nth_page( assistant, ASSIST_PAGE_INTRO );
	gtk_assistant_set_page_complete( assistant, selector, TRUE );

	g_signal_connect( G_OBJECT( assistant ), "cancel", G_CALLBACK( on_cancel ), NULL );
	gtk_widget_show_all( GTK_WIDGET( assistant ));
	gtk_main();
}

Note that if I initialize a new GtkBuilder _each time_ I run the
assistant, then all works fine. But I feel this work-around as a
waste of resources...

Note also that embedding other widgets (combobox or so) is fine,
and doesn't show the same problem.
