maybe we are looking in different places, I'm just a newbie using svn and
similar apps.

so, just to be sure ;)

I'm looking here
http://svn.m0n0.ch/wsvn/wall/tags/release-1.23b3/phpconf/inc/system.inc?op=file&rev=167&sc=1

here a copy of what I'm seeing

function system_do_extensions($early = false) {
     global $config, $g;

     if (!is_dir("{$g['etc_path']}/inc/ext") || is_dir("{$g['www_path']}/ext"))
         return;


  the parenthesis that include both the isdir is missing
