Here's a short explanation of

The unserialize() callback function will called
(with the undefined class' name as parameter), if the unserializer
finds an undefined class which should be instanciated. A warning
appears if the specified function is not defined, or if the function
doesn't include/implement the missing class. So only set this entry,
if you really want to implement such a callback-function.
