Bug? Expecting status code for size/count

[pardon-the-pun]

When running this code:

@Test
public void keys() throws Exception {
    final JRedisService jredis = new JRedisService(DefaultConnectionSpec.newSpec(url, port, 10, credentials), 1);
    jredis.keys("foobar:*");
}

I get the following output:

-- JREDIS -- BUG: serviceRequest() -- ProviderException: Bug?  Expecting status code for size/count
-- JREDIS -- INFO: serviceRequest() -- closing connection ...

Using redis-cli to try the same, works just fine.

Redis server is 1.2.6

[pardon-the-pun]

My mistake. This actually only happens against Redis server 1.3.15. Nevermind.
