1.3.3 FPDF error: Some data has already been output, can't send PDF file

[Vince007]

Hello,
I just upgraded my shop in a development environment to v1.3.3
Everything went fine except for the error i get when generating the pdf in the shop itself (pdfs work fine in BO).
I found a solution on this forum for this problem:
comment out the following line in pdf-invoice.php

include(dirname(__FILE__).'/config/config.inc.php');
//include(dirname(__FILE__).'/init.php');

What i am wondering is what are the consequences by commenting that line?
thanks for your answer(s)

greets
vince
