In long-working code to log in via the API, I have started getting this error intermittently.  The query usually works when it is retired after a short delay. 

<?xml version="1.0" encoding="utf-8"?><api><error code="internal_api_error_MWException" info="Exception Caught: Internal error in ApiLogin::execute: Unhandled case value">
