Setting prefix_key causes ErrorException

[WishCow]

I have the following config:

lsw_memcache:
    clients:
        general:
            hosts:
                - { dsn: localhost, port: 11211 }
            options:
                prefix_key: lingo_general_

This results in:

ErrorException: Warning: Memcached::setOption(): error setting memcached option in /srv/http/lingo/vendor/leaseweb/memcache-bundle/Lsw/MemcacheBundle/Cache/LoggingMemcache.php line 1087

 in /srv/http/lingo/vendor/leaseweb/memcache-bundle/Lsw/MemcacheBundle/Cache/LoggingMemcache.php line 1087

at appDevDebugProjectContainer->getMemcache_GeneralService() in /srv/http/lingo/app/bootstrap.php.cache line 211
...

If I remove the prefix_key, everything is fine.
