PDOException for Expired Memberships

Not sure if this is happening for anyone else but Recurly push notifications for expired accounts are not working. Here is the log dump:

Notice: Trying to get property of non-object in recurly_roles_recurly_process_push_notification() (line 165 of /srv/bindings/code/sites/all/modules/contrib/recurly_roles/recurly_roles.module).

Warning: array_flip(): Can only flip STRING and INTEGER values! in DrupalDefaultEntityController->load() (line 175 of /srv/bindings/code/includes/entity.inc).

PDOException: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '' for key 'name': INSERT INTO {users} (uid, created, data, uuid) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3); Array ( [:db_insert_placeholder_0] => 1929 [:db_insert_placeholder_1] => 1437751652 [:db_insert_placeholder_2] => a:1:{s:17:"mimemail_textonly";i:0;} [:db_insert_placeholder_3] => {removed for posterity} ) in drupal_write_record() (line 7333 of /srv/bindings/code/includes/common.inc).

Looks like it's failing to locate the user so it's trying to insert a new one. Since the account already exists, we're running into an issue. Checked the Webhook log and it's been happening since we updated to the current version.
