I don't know much about styles, but usually, when you get something like
this, it means that you try to do something with an empty structure whereas
the gtk expects you to have a structure which is already created, with
memory reserved etc. If you need more help, you have to post a piece of
your code -- otherwise, how can anybody know what you are doing wrong?

It seems to me that you are trying to do gtk_style_unref() on an object
which is NULL. Did you create the style you are working with using
gtk_style_new() ?

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);
    return widget;

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

Waiting for your help and thanks again!
