in my case the browser does not bring a usefull error message, therefore here is no more information displayed.

php dies silently with `PHP Fatal error:  Exception thrown without a stack frame in Unknown on line 0` and therefore the browser doesn't get enough information to show a proper error message.

I think the problem might disappear when updating php, but ATM I need to stick to 5.2 because some of my clients use those old versions on production systems..
