Description:
------------
I publish zip compressed messages in queue. If i take messages with AMQPQueue::get() for example with:

$msg = $q->get();

in $msg['msg'] i do not receive correct compressed value but some broken binary.

print_r($msg) has this output:

Array (
    [routing_key] => platform.mt.status.bond.a9bd43e4f4445679e1677898f26f35f67
    [exchange] => 
    [delivery_tag] => 1
    [Content-type] => application/json
    [Content-encoding] => gz
    [priority] => 0
    [count] => 0
    [msg] => (
              8
               5.f��d
                     @
                      �count5�
                              ��(
                                 8
                                  5.f��d
                                        @
                                         ��
)

AMQPQueue::consume() do not have this problem

Reproduce code:
---------------
$cnn = new AMQPConnection(
      array(
         'host' => '192.168.1.226',
         'vhost' => $vhost,
         'port' => 5672,
         'login' => $user,
          'password' => $pass
      )
);
$cnn->connect();
        
$q = new AMQPQueue($cnn);
        $q->declare('platform.mt.status.bond.a9bd43e4f4445679e1677898f26f35f67', AMQP_DURABLE);

$msg = $q->get();
if ($msg['count']>-1)
{
   print_r($msg);
}



Expected result:
----------------
in msg['msg'] after decompresion i expect to see:

[{"principal":"bond","guid":"cc0c7a91-b727-4aa9-9947-df6b0064e0d2","msisdn":393411223344,"operator":"H3G","ts":1316536817934}]

Actual result:
--------------
  in $msg['msg'] before decompression i see and this is invalid compressed binary
