Issue status update for http://drupal.org/node/22026

 Project:      Drupal
 Version:      cvs
 Component:    menu system

 Status:       patch

I was having this problem with a clean install of drupal 4.6.0. I had
mbstrings enabled in PHP. I turned it off, and the problem went away
immediately. Within mbstrings, I had:


mbstring.language = English
mbstring.internal_encoding = UTF-8
mbstring.http_output = auto
mbstring.func_overload = 7


PHP 4.3.11.

Menu.inc on line 974


 the do {}while() causes an error if $parent is empty because strrpos,
(I have mbstring enabled) may be null
to fix my problem I have this if statement wrapping it, which I
understand is logically equivlent to just doing a while loop.


      if ($parent){
       do {
         $parent = substr($parent, 0, strrpos($parent, '/'));
       }
       while ($parent && !array_key_exists($parent, $_menu['path
index']));
      }


This happens just after a new install.

We apparently don't check if the object exists before we work on it.

I wonder how I can reproduce this problem.  Maybe we are fixing the
symptom, not the cause.
