Broken links in taxonomy 'Summary' mode (slash not stripped)

ok, but Views has a feature that lets you accept the term name as an argument to the view (clearly using a term ID is a better approach, and I got round this problem by adjusting the view to use the tid instead). If views will accept the term name as an argument, should it not ensure that url that is generated by the 'summary, sorted' mode is an internal link to the taxonomy page (taxonomy/term/[tid]) which will always work, rather than trying to make some kind of best guess at what that path might be. In most cases it works, especially if you the 'convert dashes to spaces' - but it doesn't work if your taxonomy term as a slash in it.

As far as I could make out, it is a combination of this (theme/theme.inc, line 239):

/**
 * Preprocess theme function to print a single record from a row, with fields
 */
function template_preprocess_views_view_summary(&$vars) {
  $view     = $vars['view'];
  $argument = $view->argument[$view->build_info['summary_level']];

  $url_options = array();

  if (!empty($view->exposed_raw_input)) {
    $url_options['query'] = $view->exposed_raw_input;
  }
  $vars['classes'] = array();
  foreach ($vars['rows'] as $id => $row) {
    $vars['rows'][$id]->link = $argument->summary_name($row);
    $args = $view->args;
    $args[$argument->position] = $argument->summary_argument($row);

    $vars['rows'][$id]->url = url($view->get_url($args), $url_options);
    $vars['rows'][$id]->count = intval($row->{$argument->count_alias});
    if ($vars['rows'][$id]->url == base_path() . $_GET['q'] || $vars['rows'][$id]->url == base_path() . drupal_get_path_alias($_GET['q'])) {
      $vars['classes'][$id] = 'active';
    }
  }
}

And this (handlers/views_handler_argument_string.ing, line137):

  function summary_argument($data) {
    $value = $this->case_transform($data->{$this->base_alias}, 'path_case');
    if (!empty($this->options['transform_dash'])) {
      $value = strtr($value, ' ', '-');
    }
    return $value;
  }

That is the problem... It takes the name of the term, replaces spaces for dashes, and generates a URL from that to be used in the summary link. Shouldn't it be using the tid instead, and generating a link to /taxonomy/term/[tid] which will always work?

What do you mean by they link back to themselves?
