[TYPO3-commerce] editing of address during checkout does not send back to checkout

[Thibaut van de Mortel]

Hello list,
since the latest update I'm having this problem during checkout : if I 
edit an address (billing or delivery), then I am not redirected to 
checkout pid after submitting the form, I stay on address management pid.

The problem comes line 94 of class.tx_commerce_pi4.php :

-------------------------------------------------
t3lib_div::locationHeaderUrl($this->pi_getPageLink($this->piVars['backpid'],'',array('tx_commerce_pi3[addressType]' 
=> $this->piVars['addressType'], $this->prefixId.'[addressid]' => 
$this->piVars['addressid'])));
-------------------------------------------------

This line used to be :
-------------------------------------------------
header('Location: ' 
.$this->pi_getPageLink($this->piVars['backpid'],'',array('tx_commerce_pi3[addressType]' 
=> $this->piVars['addressType'], $this->prefixId.'[addressid]' => 
$this->piVars['addressid'])));
-------------------------------------------------


I don't know why the "locationHeaderUrl" of t3lib_div fails, because it 
is given the correct link (same link as old version).
I switched back to old version of this line and everything works fine again.

Am I the only one having this?
