<p>It uses the same rules_config property to store either the string or the object. The problem arises when this entity is cached in entity_load(), so the first entity_load() call returns a string in this property, and the second entity_load() call returns the object loaded by rules_config_load(). This is the common case if you define both 'update rule' and 'validation rule' for the same entity bundle.</p>
<p>The proposed patch adds checking of value type of rules_config property.</p>
