Batch Broken?

[indolering]

Any/all of these function calls are generating a parse error:

      var batch = [
        { method: 'getblockcount',params: []},
        { method: 'name_filter', params: ["", 20, 0, 0]},
        { method: 'getnewaddress', params: ['myaccount']}
      ];

      client.cmd(batch, function(err, dataset) {
        //err.code: -32700
        //err.message: Parse error
      }
