Hi, experts, I found following codes will crash in gnome 2.21 environment: ... GtkWidget *foo = gtk_invisible_new(); gtk_widget_unref(foo); ... But it works well if gtk_widget_unref() is replaced with gtk_widget_destroy(). Does that mean that we can't use gtk_widget_unref() on such object and we can only use gtk_widget_destroy() to release it?
