Q:

I'm getting a '500 Internal Server Error' when I try adding menu items

For some reason, I suddenly get 500 Internal Server Error when I try to add menu item to a menu and I can't figure out why.
I'm running Apache2 with Centos 6 OS on a VPS.
I have PHP 5.8 and MySQL 5.1
This is the error message:

Internal Server Error
The server encountered an internal error or misconfiguration and was
  unable to complete your request. (...)

My error_log file shows nothing.  
I can create new menus
I can not add pages or custom links to menu items
I've deleted the .htacess file and get the same error
I can add new pages and posts

Can anyone help me to figure out what may cause this weird problem?

A:

I found this message from Mark Jaquith, WP lead developer:

The WordPress core team is quite aware of this issue, and it is
  absolutely something that needs to be solved. It is an issue with how
  the menus are saved. Too much data is passed back. It takes a lot of
  memory and computation time, and many servers are configured to have
  limits on the number of vars you can POST in one request.
  Unfortunately, we just couldn't reach a consensus on the best way to
  solve it in time for WordPress 3.2. So for this release, it will have
  to remain a known issue that menu saving performance degrades or
  generates errors beyond a certain point (which may vary from server to
  server).
The Trac ticket has been tagged as 3.3-early, which means we'll put it
  as high priority early in the 3.3 development cycle.
I appreciate your feedback and for holding us to a high standard! This
  is how things get better.

The question is, when will t his be fixed? :-/
