I was trying to set up Memcached on my machine, and for some reason I used the JSON serialiser. Unfortunately, this is broken. It seems that any array that is passed to the cache is then retrieved as an stdClass. Which causes Fatal errors everywhere.
I kept all the default settings for Memcached, apart from the serialiser obviously. And I used this store as the default for Application cache.
Fatal error: Cannot use object of type stdClass as array in /home/fred/www/repositories/sm/moodle/lib/pluginlib.php on line 3346
