The same problem causes throwing exceptions in function __autoload.

I think this behavior is against the logic of exceptions. Excellent  
feature of PHP 5.3 would be to resolve this errors.



This is down to the design of the engine, we perform casting to  
strings in a lot of different places and it couldn't be guaranteed  
that the engine would handle any exceptions correctly.

I'm pretty sure there is something in the internals archives about  
this change.
