Notice: Undefined index: path in imagecache_token_tokens() (line 94 of .....imagecache_token.module)

The isset($attribute) at line 93 in the module file should probably check the $field attributes if I understand the intent correctly:

        if ($attribute == 'render') {
          $output[] = theme('image_formatter', array('item' => $field, 'image_style' => $type));
        }
        elseif (isset($attribute) && !empty($attribute)) {
          $output[] = $field[$attribute];
        }
        else {
          $output[] = image_style_url($token, $field['uri']);
        }

Like so:

        if ($attribute == 'render') {
          $output[] = theme('image_formatter', array('item' => $field, 'image_style' => $type));
        }
        elseif (isset($field[$attribute]) && !empty($attribute)) {
          $output[] = $field[$attribute];
        }
        else {
          $output[] = image_style_url($token, $field['uri']);
        }
