EntityMalformedException: Missing bundle property on entity of type taxonomy_term

Recientemente tuvimos este error en Drupal 7:

EntityMalformedException: Falta la propiedad "bundle" en la entidad de tipo taxonomy_term. en entity_extract_ids() (línea 8090 de /home/mysite/mysite.com/public/includes/common.inc).

Y esta fue la solución:
