Patch Level 3 caused a bug

[squishi]

I am reporting this here, because it is the forum that offers help and assistance. On vbulletin.com, the only support that I will get is being told to reset the whole forum, remove all plugins and reinstall everything. No thank you - I've been told that one too many times.

I was unable to fix the problem. Maybe it was not the plugin afterall - I cannot tell. What I know is that it worked recently.

Actually, when doing a backtrace in functions.php > fetchuserinfo(), I see that fetch_userinfo is called from VB_Session in init.php.
$vbulletin->userinfo is only defined a couple of lines later in init.php.
$vbulletin->userinfo is undefined in the fetch_userinfo_query hook.

PHP Code:

// build the session and setup the environment
$vbulletin->session =& new vB_Session($vbulletin, $sessionhash, $vbulletin->GPC[COOKIE_PREFIX . 'userid'], $vbulletin->GPC[COOKIE_PREFIX . 'password'], $styleid, $languageid);

// Hide sessionid in url if we are a search engine or if we have a cookie
$vbulletin->session->set_session_visibility($show['search_engine'] OR $vbulletin->superglobal_size['_COOKIE'] > 0);
$vbulletin->userinfo =& $vbulletin->session->fetch_userinfo(); 


The backtrace in functions.php > fetchuserinfo() goes like this:

#0 fetch_userinfo(1, 0, 0) called at [/www/virtual/forum/includes/class_core.php:2745]
#1 vB_Session->vB_Session(vB_Registry Object ...)
#2 require_once(/www/virtual/forum/includes/init.php) called at [/www/virtual/forum/global.php:21]
#3 require_once(/www/virtual/forum/global.php) called at [/www/virtual/forum/index.php:59]

In words:
fetch_userinfo() is called in the vB_Session class in class_core.php. VB_Session is called in init.php, before $vbulletin->userinfo is defined. The "global" statement in fetch_userinfo() will fail. $vbulletin->userinfo is null.

Can somebody confirm that $vbulletin->userinfo is undefined in their fetch_userinfo_query hook?
