In general, I'd say a warning from within the wrapper would be nice.

But there's something different wrong here: I use GTK+ 2.2.2.
gtk_tree_path_append_index asserts index >= 0:

  g_return_if_fail (index >= 0);

Despite that, when I do something like:

  my $path = Gtk2::TreePath -> new_from_indices(1, 0, -1);
  print $path -> to_string(), "\n";

or

  my $path = Gtk2::TreePath -> new("1:0");
  $path -> append_index(-1);
  print $path -> to_string(), "\n";

"1:0:-1" is printed. Can anyone shed some light on this?
