Two deep chained API not working after upgrade to 4.3.3

This chained api worked before the site was upgraded to civicrm 4.3.3 but anymore:

[code] $params = array(
'group_id' => 4,
'status' => 'Added',
'version' => 3,
'sequential' => 1,
'api.contact.get' => array(
'sequential' => 1,
'contact_is_deleted' => 0,
'api.profile.get' => array(
'profile_id' => 15,
),
),
);[/code]

The chaining still works like this if the chaining is one deep:

[code]$params = array(
'group_id' => 4,
'status' => 'Added',
'version' => 3,
'sequential' => 1,
'api.contact.get' => array(
'sequential' => 1,
'contact_is_deleted' => 0,
),
);[/code]

Nothing else had changed so I'm fairly certain it had something to do with the upgrade.
