 When enable-trans-sid is ON in php.ini - PHP transforms all generated contents, regardless of its actual type, but it should only do it for HTML (XHTML, WML and so on) contents.
 For example take a look at this example:

<?php
header('Content-type: text/plain');
session_start();
echo '<html><body><a href="test.php">test</a></body></html>';
?>

 Generated content is HTML, but actual type of generated content is text/plain and hence it have nothing to do with sessions. But content transformation still occurs and resulted output is:

<html><body><a href="test.php?PHPSESSID=135a5afcbbf97014a56caf4bd8c4200b">test</a></body></html>

instead of expected:

<html><body><a href="test.php">test</a></body></html>

 Even more interesting things may appear when somebody will try to output som mixed code+text content when there will be something like HTML link.

 Suggested way to fix is to add a parameter to php.ini where will be listed MIME types of content, which should be transformed.

Not really bug, but a feature request. 
Fast solution: Never use trans-sid, it's unsafe anyway.

With output buffer, header() can may be called anywhere. 
Therefore, fixing this involves rewriting output buffers which is not feasible.

You should control it via session.use_trans_sid.
