class::method() isn't a static call in PHP (it isn't always a static call in C++ either).
The primary use for class::method() is actually calling methods from your parent class, not calling 'static methods' (the ability to create static classes and call their methods is pretty much a positive 'side effect').

So, this is the intended behavior.

If you call a static method from within an object, the static method will inherit the $this pointer of the calling object. This script demonstrates the problem:

<?php

error_reporting(E_ALL);

class StaticClass {
    function doSomething() {
        echo $this->data;
    }
}

class Instantiated {
    var $data;

    function Instantiated($data) {
        $this->data = $data;
        StaticClass::doSomething();
    }
}

$ob = new Instantiated('foo');

?>

This is rather confusing behavior - $this should be out of scope inside static methods no matter what.
