C/GTK - Packing GtkImage inside GtkEventBox loses reference

[Marcus Reis <marcus lanhelp com br>]

Hi all, I'm newbie in C / GTK and trying to build a simple game. I got
this callback function:

#########################################################################
static GtkWidget *cria_quadrante(int tipo)
{
GtkWidget *image;
GtkWidget *event_box;

g_print("%d",tipo);

if(tipo==0) image = gtk_image_new_from_file ("img/n.png");
else if(tipo==1) image = gtk_image_new_from_file ("img/o.png");
else image = gtk_image_new_from_file ("img/x.png");

event_box = gtk_event_box_new ();

//g_object_ref(image);

gtk_container_add (GTK_CONTAINER (event_box), image);

g_signal_connect (G_OBJECT (event_box), 
                      "button_press_event",
                      G_CALLBACK (movimento_do_jogador),
                      image);
return event_box;
}
#########################################################################


The callback function movimento_do_jogador() is connected to
"button_press_event" of GtkEventBox, look at it:


#########################################################################
static void movimento_do_jogador(GtkWidget *widget, GtkWidget *image)
{
const gchar *posicao = gtk_widget_get_name(widget);

gtk_image_set_from_file(GTK_IMAGE (image), "img/o.png");

g_print("Voce clicou no quadrante %c-%c n", posicao[2], posicao[4]);
}
#########################################################################

That's it, the code above gives me a SEGFAULT in
gtk_image_set_from_file(). The objective is when user clicks on images
the image changes to another trough the function. I'm really messy with
child widgets access...

Thanks in advance.
