Error with update.php

I just switched to 2.6 from 2.5.1 and when I went up automatically update my plugins I get the following error message

Warning: extract() [function.extract]: First argument should be an array in /home/sinfullo/public_html/wp-admin/update.php on line 38

This what I have for lines 33 through 41:

$hostname = '';
	$username = '';
	$password = '';
	$ssl = '';
	if ( !empty($credentials) )
		extract($credentials, EXTR_OVERWRITE);
	if( $error )
		echo '<div id="message" class="error"><p>' . __('<strong>Error:</strong> There was an error connecting to the server, Please verify the settings are correct.') . '</p></div>';
?>

Does anyone know how to fix this?
