Treeview help needed

[wilfried kopp <wilfried kopp wanadoo fr>]

Hi everybody,

I am stuck with a segmentation fault caused by a treeview and I have pent hours trying to figure out what's wrong with no success.


Here is how I create the model (I simplified the code... but this version crashes as well...)
  while (item)
    {
      gtk_list_store_append (store, &iter);
      gtk_list_store_set (store, &iter,
			  MIME_TYPES_TO_SKIP_COLUMN_STATE, 0 ,
			  MIME_TYPES_TO_SKIP_COLUMN_MIME_TYPE, test,
			  -1);

      item=g_list_next(item);
    }

The segmentation fault happens when I remove an item with this code:
 gtk_tree_model_get (model,&iter,
  		      0, &state, 
  		      1, &mime_type,
		      -1);

  if (gtk_tree_selection_get_selected (listSelection, NULL, &iter))
  {
    gtk_list_store_remove (GTK_LIST_STORE (model), &iter);
  }


Here is what ddd says:
(gtktalog:5396): Gtk-CRITICAL **: file ../../gtk/gtkliststore.c: line 566 (gtk_list_store_get_value): assertion `GTK_LIST_STORE (tree_model)->stamp == iter->stamp' failed
