Hhvm nginx toString error with Magento Magmi

I am trying to run the magmi product import plugin in a Magento application that runs on an aws ec2 instance that has NGINX and HHVM on it. When I try to run the magmi product import application on Magento, I get an error below the server in my hhvm error log .

/var/log/hhvm/error.log

\nCatchable fatal error: Object of class Magmi_ProductImportEngine could not be converted to string in /var/www/qa-hoi/magmi-importer/inc/magmi_mixin.php on line 9

This is magmi_mixin.php file

<?php
class Magmi_Mixin
{
    protected $_callers;

    public function bind($caller)
    {
        $this->_callers[]=$caller;
        $this->_callers=array_unique($this->_callers);  // LINE 9   
    }

    public function unbind($caller)
    {

        $ks=array_keys($this->_callers,$caller);
        if(count($ks)>0)
        {
            foreach($ks as $k)
            {   
                unset($this->_callers[$k]);
            }
        }

    }

    public function __call($data,$arg)
    {
        if(substr($data,0,8)=="_caller_")
        {
            $data=substr($data,8);
        }
        for($i=0;$i<count($this->_callers);$i++)
        {
            if(method_exists($this->_callers[$i],$data))
            {
              return call_user_func_array(array($this->_callers[$i],$data), $arg);
            }
            else
            {
                die("Invalid Method Call: $data - Not found in Caller");
            }
        }
    }
}

Any idea how I should solve this? Should I update the php.ini file?

Which can cause a fatal error. This does not happen on my local Apache machine.

UPDATE

I installed HHVM on my local machine and ran xdebug. It seems that the object $callerin the magmi file contains several arrays that cannot be evaluated. See screenshot below:
