Invalid command cursor on listCollections with a sharded cluster in MongoDB 3.2

Install mongo-orchestration and start a sharded cluster:

mongo-orchestration -b 127.0.0.1 -p 8889 --no-fork start
curl -XPUT http://localhost:8889/v1/sharded_clusters/myCluster --data @configurations/sharded_clusters/clean.json

Then, run the included PHP script:

$ php invalid-cursor-listCollections.php
PHP Fatal error:  Uncaught exception 'MongoCursorException' with message 'localhost:27017: the command cursor did not return a correctly structured response' in invalid-cursor-listCollections.php:7

<?php
$client = new MongoClient();
$client->dropDb('invalid-cursor-test');
$db = $client->selectDb('invalid-cursor-test');
$db->listCollections();
