Invalid input syntax for integer: "autocomplete" with entitycache

After installing the module, I wanted to create a new Terms of Use, so I went to admin/config/people/terms_of_use.
I received the following error:

PDOException: SQLSTATE[22P02]: Invalid text representation: 7 ERROR: invalid input syntax for integer: "autocomplete" LINE 5: WHERE (base.nid IN ('autocomplete')) ^: SELECT revision.vid AS vid, base.uid AS uid, revision.title AS title, revision.log AS log, revision.status AS status, revision.comment AS comment, revision.promote AS promote, revision.sticky AS sticky, base.nid AS nid, base.type AS type, base.language AS language, base.created AS created, base.changed AS changed, base.tnid AS tnid, base.translate AS translate, revision.timestamp AS revision_timestamp, revision.uid AS revision_uid FROM {node} base INNER JOIN {node_revision} revision ON revision.vid = base.vid WHERE (base.nid IN (:db_condition_placeholder_0)) ; Array ( [:db_condition_placeholder_0] => autocomplete ) in EntityCacheControllerHelper::entityCacheLoad() (line 95 of /srv/http/d7.rovin.be/sites/all/modules/entitycache/entitycache.module).

PostgreSQL 9.1, Entity Cache and i18n installed.

Probably the error is the use of #autocomplete_path => 'node/autocomplete' in the terms of use module.
I assume this should be 'terms_of_use/autocomplete' instead of node/autocomplete.
