I'm getting this weird error when running cron via Drush:

% /usr/local/bin/drush -r /srv/www/sites/example.com/builds/current -l example.com cron
PHP Fatal error:  Call to protected method EntityCacheControllerHelper::entityCacheSet() from context 'EntityAPIController' in /srv/www/sites/example.com/builds/v1.0.0-beta.16/profiles/sfera/modules/entity/includes/entity.controller.inc on line 288
Drush command terminated abnormally due to an unrecoverable error.

This seems to be related to the Entity Cache module somehow, but not completely sure.
