GTK should do free memory it owns.  If you have used a pixbuf that you
loaded in from a file, you have a reference count of 1 on it and it is up to
you to free it.  For example,

        GdkPixbuf *pb = NULL;

        pb = (...) /* load from file */
        gtk_image_set_image_from_pixbuf(GTK_IMAGE(myimage), pb);

        /* YOU MUST UNREF THE PIXBUF */
        g_object_unref(G_OBJECT(pb));
