Before I unref and clear the ListStore I'm running 
gtk_tree_view_set_model (GtkTreeView *, NULL) on the TreeModel.

However there's a GtkTreeModelSort which holds the ListStore, this 
GtkTreeModelSort is then added to the TreeView.

I didnt find a way to unset the GtkTreeModelSort and the ListStore, but 
before I clear and unref the ListStore, I unref the GtkTreeModelSort.


    gtk_tree_view_set_model ( ddisplay , NULL );
    //unref to the TreeModelSort
    g_object_unref ( G_OBJECT ( inter_sort ) );

    gtk_list_store_clear (store);
    g_object_unref( G_OBJECT (store) );

Setting export G_SLICE=always-malloc did nothing.
