It should fail with securepoll-remote-parse-error without generating a PHP warning. Maybe it should log something anyway, it shouldn't be failing on 1 in every 1000 requests, but that's probably a subject for another bug.

Evaluation:

Obscure issue. We should add a logging that provides more information about the root cause. Best guess it that the auth-api.php script crashes and returns an unexpected output
