Thanks very much!

I do no 'gtk_style_unref' in my code,The problem come out when I want destroy(gtk_widget_destroy) some 
widget, but I don't know why the problem does not happen every time,sometimes it's OK:( .

There is some code in my app for create widget ,I think it maybe help your to debug:

GtkWidget *gapp_notebook_new(char *name)
{
    GtkWidget *widget;

    widget = gtk_notebook_new();
    if(widget==NULL) /*create failed*/
        return NULL;
    gtk_widget_ref (widget);
    gtk_object_set_data_full (GTK_OBJECT (gapp_main_window),name,widget,
        (GtkDestroyNotify) gtk_widget_unref);
    gtk_widget_set_name(widget,name);
    return widget;
}

then, when I destroy it,the problem come out :(

Waiting for your help and thanks again!
