ugh - if you want to override the constructor that's fine - do it using

public function __construct() {}

PHP 5 uses unified constructors - the "use the same function as the 
class name" support is a holdover for BC, please please don't use it in 
new code.... as you see it has some seriously odd side effects

see the manual http://php.net/oop5.decon
