Drupal 7 Solr索引错误显示“EntityMalformedException：类型taxonomy_term的实体上缺少bundle属性”

Question

在Drupal 7.14中，当我索引整个站点时，Solr显示以下错误：

AJAX HTTP error occurred. HTTP Result Code: 500 Debugging information follows. 
Path: /batch?id=1938&op=do StatusText: Service unavailable (with message)
ResponseText: EntityMalformedException: Missing bundle property on entity of type taxonomy_term. in entity_extract_ids() (line 7539 of /project/path/includes/common.inc).

所以当我查看/includes/common.inc中的行（围绕行：7537）时：

// Explicitly fail for malformed entities missing the bundle property.
if (!isset($entity->{$info['entity keys']['bundle']}) || $entity->{$info['entity keys']['bundle']} === '') {
  throw new EntityMalformedException(t('Missing bundle property on entity of type @entity_type.', array('@entity_type' => $entity_type)));
}

• 那些代码（common.inc）实际上是在做什么？
• 我如何克服这个错误？

请尝试使用此模块https://drupal.org/project/taxonomy_orphanage，它将删除所有空捆绑包。
