if output_buffering is set to 4096 and trans_sess_id is used, the output may be broken:

In the reproduce example, the trans_sess_id writes
<a href="/translators/index.php/calendar/view" ?phpsessid="fa562d5bb14df890e6db68627ea76442">

Reproduce code:

htaccess includes:

php_value session.use_cookies 0
php_value session.use_trans_sid 1 
php_value output_buffering 4098

test.php just sets up enough variables to render the HTML

home.html.en.php is just a HTML which happens to have the url link in the right place to reproduce the bug.

Expected result:
on the "View your personal calendar": 

<a href="/translators/index.php/calendar/view?phpsessid=fa562d5bb14df890e6db68627ea76442">

Actual result:
on the "View your personal calendar": 

<a href="/translators/index.php/calendar/view" ?phpsessid="fa562d5bb14df890e6db68627ea76442">
