debugger.php errors when $persistentModel = true

Hi,

I tried including $persistentModel = true as suggested here :
http://www.pseudocoder.com/archives/2009/03/17/8-ways-to-speed-up-cakephp-apps/comment-page-1/

Well it did increase the speed of my app (about 200%) but I'm
receiving this error when debug != 0

Catchable fatal error: Object of class __PHP_Incomplete_Class could
not be converted to string in cake\libs\debugger.php on line 451

Any ideas bakers?
