[TYPO3-english] Could not analyse class:Tx_Fluid_Core_Widget_WidgetRequestHandler maybe not loaded or no autoloader

[Domi]

Hello,

I am completely banned from all my local installations. After an update 
of my linux to PHP version 5.4.3 all my local projects giving following 
exception in front and backend, only install tool is accessible:

Could not analyse class:Tx_Fluid_Core_Widget_WidgetRequestHandler maybe 
not loaded or no autoloader

Tested in TYPO3 4.6 & 4.7.

Thanks for any hints,

Dominic
