I noticed in deployment-bastion:/data/project/logs/fatal.log three failures in the last hour: 25-Jan-2014 06:02:02, 06:32:02 and 7:02:01 in Flow's SpamFilter setup, e.g.:

[25-Jan-2014 07:02:01] Catchable fatal error: Argument 1 passed to Flow\SpamFilter\AbuseFilter::__construct() must be an instance of User, null given, called in /data/project/apache/common-local/php-master/extensions/Flow/container.php on line 432 and defined at /data/project/apache/common-local/php-master/extensions/Flow/includes/SpamFilter/AbuseFilter.php on line 25

these aren't from the beta labs, they are on deployment-jobrunner08. I suspect they are occurring when our Continuous Infrastructure tries to set up an MW environment, but I'm not sure why it didn't happen earlier.  The code is 
  $c['user'] = $GLOBALS['wgUser'];
so maybe there is no wgUser when running a maintenance script.  Code could check for this, or avoid setting up a controller.abusefilter when running maintenance scripts.

The most recent backtrace in fatal.log is
