I start getting this error:
Warning: Illegal offset type in isset or empty in references_handler_argument->title_query() (line 32 of ...\sites\all\modules\references\views\references_handler_argument.inc).
Discovered that in this code snippet

 foreach ($this->value as $key) {
      if (isset($results[$key])) {
        $titles[] = check_plain($results[$key]);
      }
}

$results[$key] is array and that causes error.
I'm using Panels and contexts from referenced node, maybe there is the problem.

I had the same problem. The cause was sending arguments inside an array, instead of plain values. The view manages to extract the value and use it, but some functions (like this one and some token-related functions) expect non-array arguments. HTH.

Same problem here. Everything works fine but this error message appears.
