From manual page: http://www.php.net/gearmanjob.setreturn%23Description

Manual reads that parameter of function GearmanJob:setReturn is string while it 
should be integer (long).

Test script:
---------------
#!/usr/bin/env php
<?php

$worker = new GearmanWorker();
$worker->addServer();
$worker->addFunction('listRepo', 'listRepoCallback');
while ($worker->work());

function listRepoCallback($job)
{

            $result = shell_exec(
                    'svn ls --username=yyyy --password=xxxxx '
                    . 'https://project.svn.beanstalkapp.com/main/trunk');
  $job->setReturn(json_encode($result));
}

?>


Expected result:
----------------
Script executing without a problem.

Actual result:
--------------
PHP Warning:  GearmanJob::setReturn() expects parameter 1 to be long, string 
given in /home/ubuntu/listGmWorker.php on line 23
