Description:
------------
Hi,

The Amazon Service can return the response in chunks. This is (currently) not supported by HTTP_Request.
An easy fix is to go back to HTTP/1.0.

In AmazonECS4.php, line 928:

$http = &new HTTP_Request($url);
$http->setHttpVer ('1.0') ; /////////
$http->addHeader('User-Agent', 'Services_AmazonECS4/' . $this->getApiVersion());
$http->sendRequest();

Test script:
---------------
$options = array();
$options['Operation'] = 'ItemSearch';
$options['Artist'] = 'Jem';
$options['SearchIndex'] = 'Music';
$options['ResponseGroup'] = 'Small,BrowseNodes';
$options['Sort'] = 'orig-rel-date';
$options['ItemPage'] = 1 ;
$options['locale'] = 'us' ;
$result = $this->_sendRequest($options);
print_r ($result) ;

The data cannot be unserialised, but it is incomplete. It's incomplete because only the first chunk is read...

Thank you for reporting!

I have tested the script, and it works fine for me.
Why?

Hmm, no idea.
Is it possible you don't use the latest HTTP_Request class?
I saw in the http sniffer that the data comes back in
chunks and that thus only the first 32K was present in the
responsebody. Hence the XML unserializer chocked on it...
