"Link this field to node" suddenly broken

Strangest thing. Suddenly, all the linked node titles in any view with a node: title fields selected to "Link this field to node" have disappeared. Link/title gone from view display.

If I remove the Link this field to node checkbox, the title returns (without link). This is completely out of the blue. The only change made recently was adding apachesolr search module to the site.

I realize I can use the "Out put field as link" method with tokens, however I have many many views using the link this field to node method.

Not sure if this is related, but when I try to dump $data & $values in function render_link($data, $values) in views_handler_field_node.inc they are empty, even though they are populated when I look at render($values).

  /**
   * Render whatever the data is as a link to the node.
   *
   * Data should be made XSS safe prior to calling this function.
   */
  function render_link($data, $values) {
   dpm($data); // empty
   dpm($values); // empty
    if (!empty($this->options['link_to_node']) && $data !== NULL && $data !== '') {
      $this->options['alter']['make_link'] = TRUE;
      $this->options['alter']['path'] = "node/" . $values->{$this->aliases['nid']};
      if (isset($this->aliases['language'])) {
        $languages = language_list();
        if (isset($languages[$values->{$this->aliases['language']}])) {
          $this->options['alter']['language'] = $languages[$values->{$this->aliases['language']}];
        }
        else {
          unset($this->options['alter']['language']);
        }
      }
    }
    return $data;
  }

  function render($values) {
    dpm($values) // populated as is first argument below.
    return $this->render_link(check_plain($values->{$this->field_alias}), $values);
  }

marking as support request until anyone else confirms this...thanks.
