That's inside the functions that instantiate new class objects (such as 
GeneralUtility::makeInstance()). If some code requests a class that 
doesn't exist you'll get such an error.

Search in the extensions for this class name and you'll know what to adjust.

This seems to be a (rare) case where the Install Tool can't catch the 
error and lead you to a screen where you can uninstall (disable) the 
affected extension. Will you let us know if you found the extension and 
in which file the problematic call was?
