Change To this and check to see if it works.

        GtkWidget *week_select_store;  <== Make sure this actually points to a store.
>       GtkTreeIter row_pointer;   <== This should not be a poiter !!! else you will
have to allocate mem.

address &*/);   
        while(ret_val_bool)
        {
                ret_val_bool = gtk_list_store_remove    \
                                (GTK_LIST_STORE(week_select_store), &row_pointer  /* this again is the
address &*/);
        }

 
 Let me know the results.

 Hope this helps.
