Patch Level 3 caused a bug

[squishi]

The fetch_userinfo function itself checks for $vbulletin->userinfo. So something is broken in the original code already.
I can work around it, but I know other plugins check for $vbulletin->userinfo as well.
What bugs me is that it used to work a few days ago.
And since $vbulletin->userinfo is not available and I have no way to check if a user is logged in in that hook, it is not a good idea to just leave it like this.

Something's broken and there seems to be a flaw in the vb code. I checked a freshly downloaded code (patch level 3), and it follows the same logic.

init.php calls vb_session. vb_session calls fetch_userinfo, and $vbulletin->userinfo is not defined in this function.
Now let's assume that this call to fetch_userinfo() is not the call that loads this plugin. This would mean that the hook is executed twice. That would be extremely inefficient.

For example, the vbulletin blog product uses $vbulletin->userinfo['permissions'] in the fetch_userinfo_query hook.
