zen theme('breadcrumb') not consistent when called outside of theme page.

I'm currently writing a module that uses theme('breadcrumb') outside of theme('page'). i.e. I have a custom menu callback that also outputs the breadcrumbs.

At present, because zen_preprocess_page is not called, my breadcrumbs do not have the title of the current page appended on the end. I tried adding the title to the end of the breadcrumb array, and while this showed the title, it also resulted in the trailing separator to be shown after it.

I tracked this down to the title being 'injected' into the breadcrumbs in zen_preprocess_page. Whilst I could do the same, I do not want to resort to this method.

I feel it would make more sense to append the title in zen_breadcrumb instead.

Something like:

    // Return the breadcrumb with separators
    if (!empty($breadcrumb)) {
      $breadcrumb_separator = theme_get_setting('zen_breadcrumb_separator');
      $trailing_separator = (theme_get_setting('zen_breadcrumb_trailing') || theme_get_setting('zen_breadcrumb_title')) ? $breadcrumb_separator : '';
      $return  = '<div class="breadcrumb">' . implode($breadcrumb_separator, $breadcrumb) . $trailing_separator;
      if (theme_get_setting('zen_breadcrumb_title')) {
        $return .= drupal_get_title();
      }
      $return .= "</div>";
      return $return;
    }

Does this seem like a reasonable request? This way, theme('breadcrumb') can be called from anywhere, and will always return the same HTML.
