URGENT: Comments from Anon users have dissapeared?

Could this be a bug?
I know that claiming to have found a bug isn´t gracious, but I´ve found several people with this issue unresolved; nobody answers, nor knows what to do about it:

• Another Issue
• Another one, this time there´s a solution, but didn´t work for me
• Another one
• Another one
• Another one (clearing the cache didn´t worked either).

There are more, but this three seems to have the exact problem...

The things that I made were:
1 - Adding some profile fields (the profile module was already activated)
2 - Install Usernode, Nodeprofile and Nodefamily modules.
3 - Added some views using nodeprofiles.
4 - Didn´t created any profile template, but I did create a usernode template.
5 - Added to my template.tpl.php file a certain stuff from Views.template module (a recent one added by merlinofchaos that creates code to add to the template file).
6 - Added code to my template.tpl file to point people to their usernode instead their profile. That code was provided by the usernode module, inside the installation folder.

I think that step 6 could just push the wrong button somewhere and made all crash.
Don´t understand whow, though.

The code that I´ve added was this:

Views Stuff added to template.tpl.php (step 5):

...

/**
 * views template to output a view.
 * This code was generated by the views theming wizard
 * Date: Dom, 21/01/2007 - 22:53
 * View: Directorio
 *
 * This function goes in your template.php file
 */
function phptemplate_views_view_table_Directorio($view, $nodes, $type) {
  $fields = _views_get_fields();

  $taken = array();

  // Set up the fields in nicely named chunks.
  foreach ($view->field as $id => $field) {
    $field_name = $field['field'];
    if (isset($taken[$field_name])) {
      $field_name = $field['queryname'];
    }
    $taken[$field_name] = true;
    $field_names[$id] = $field_name;
  }

  // Set up some variables that won't change.
  $base_vars = array(
    'view' => $view,
    'view_type' => $type,
  );

  foreach ($nodes as $i => $node) {
    $vars = $base_vars;
    $vars['node'] = $node;
    $vars['count'] = $i;
    $vars['stripe'] = $i % 2 ? 'even' : 'odd';
    foreach ($view->field as $id => $field) {
      $name = $field_names[$id];
      $vars[$name] = views_theme_field('views_handle_field', $field['queryname'], $fields, $field, $node, $view);
      if (isset($field['label'])) {
        $vars[$name . '_label'] = $field['label'];
      }
    }
    $items[] = _phptemplate_callback('views-table-Directorio', $vars);
  }
  if ($items) {
    return theme('item_list', $items);
  }
}
......

Usernode stuff added to template.tpl.php (Step 6)

...

/**
 * Catch the theme_username function and link to the usernode instead of linking to the userpage
 */

function phptemplate_username(&$object) {

  if ($object->uid && $object->name) {

      $name = drupal_substr($object->name, 0, 15) .'...';
    }
    else {
      $name = $object->name;
    }

    if (user_access('access content') && module_exist('usernode')) {
      $nid = usernode_get_node_id($object);
      $output = l($name, 'node/'. $nid, array('title' => t('View user details.')));
    }
    else {
      $output = check_plain($name);
    }
  }
  else if ($object->name) {
    // Sometimes modules display content composed by people who are
    // not registered members of the site (e.g. mailing list or news
    // aggregator modules). This clause enables modules to display
    // the true author of the content.
    if ($object->homepage) {
      $output = l($object->name, $object->homepage);
    }
    else {
      $output = check_plain($object->name);
    }

    $output .= ' ('. t('not verified') .')';
  }
  else {
    $output = variable_get('anonymous', 'Anonymous');
  }

  return $output;
}

/**

 */

function phptemplate_user_picture(&$account) {
  if (variable_get('user_pictures', 0)) {
    if ($account->picture && file_exists($account->picture)) {
      $picture = file_create_url($account->picture);
    }
    else if (variable_get('user_picture_default', '')) {
      $picture = variable_get('user_picture_default', '');
    }

    if (isset($picture)) {
      $alt = t('%user\'s picture', array('%user' => $account->name ? $account->name : variable_get('anonymous', 'Anonymous')));
