Warning: array_flip() [function.array-flip]: Can only flip STRING and INTEGER values! [#1829538]

I'm getting the error below when searching items in relation widget.
Warning: array_flip() [function.array-flip]: Can only flip STRING and INTEGER values! in DrupalDefaultEntityController->load() (line 178 of Z:\home\erpal.local\www\includes\entity.inc).

That's because $entity_id is passed in array in entity_load_single function in theme.inc file.
There should be line:
$entity = entity_load_single($entity_type, $entity_id);
instedd of :
$entity = entity_load_single($entity_type, array($entity_id));

Here is my patch:

entity_load_single() is indeed expecting the second parameter to be just the id. It was actually my fault, see #1807196: Strict warning using reset() on non-variable. Sorry.
