While you are correct that it might be more logical to reverse the order, this 
isn't a huge problem.

Description:
------------
The method Exception::__toString() creates the message in the wrong order if a previous exception
exists in the Exception object.

The message contains the message from the previous exception as first and then marked as next
exception the message from the exception object itself. Normally the message from the current
exception should be the first message followed by the previous message and so one.

Test script:
---------------
<?php

try {
    throw new Exception("Previous exception");
} catch (Exception $previous) {
    $current = new Exception("Current exception", 0, $previous);

    echo 'Previous:' . $current->getPrevious()->getMessage() . '<br
/>';
    echo 'Current:' . $current->getMessage() . '<br />';
    echo 'String:' . $current->__toString() . '<br />';
}


Expected result:
----------------
Previous: Previous exception
--------------------------------------------------------------
Current: Current exception
--------------------------------------------------------------
String: exception 'Exception' with message 'Current exception' in
exception.php:4 Stack trace: #0 {main} Next exception 'Exception' with message
'Previous exception' in exception.php:6 Stack trace: #0 {main}

Actual result:
--------------
Previous: Previous exception
--------------------------------------------------------------
Current: Current exception
--------------------------------------------------------------
String: exception 'Exception' with message 'Previous exception' in
exception.php:4 Stack trace: #0 {main} Next exception 'Exception' with message
'Current exception' in exception.php:6 Stack trace: #0 {main}
