<p>Done.</p>

I've been dealing with this this morning too. Even the simplest Matrix field causes this recursion error.

It's somewhat comforting to know that I'm not alone in this. <=) I hope we will have a solution to this soon!
I'm heading home now, so no more trouble shooting on my part until tomorrow morning. =/ I'll post if I've heard anything from support when I'm back at the office.

Brad was right, it was xDebug that was the culprit. So here's what I did:

In the Linux terminal I ran:
sudo gedit /etc/php5/mods-available/xdebug.ini

In the xdebug.ini file I added the line below and saved.
xdebug.max_nesting_level=256

In the Linux terminal I ran:
sudo service apache2 restart


Done.

Note: if the this does not fix it, try changing the command in step 1 to:
sudo gedit /etc/php5/conf.d/xdebug.ini

or just edit your php.ini file where ever it may be located.
