functions are not seeing uri segments

[eluser]pransome[/eluser]
I set $config['uri_protocol'] = "REQUEST_URI"; (have tried all the options here)
and when I browse to "http://localhost:8888/RC/index.php/password/test/index"
with the Controller code below I see:

--- segmentOne:

So somehow the segments are getting lost.

Controller code:

<?php

class Password extends Controller {
function index() {
//echo 'Password';
}

function test() {
echo uri_string();
echo ' --- ';
$segmentOne = $this->uri->segment(1);
echo 'segmentOne: '.$segmentOne;
//echo ' --- ';
//echo $_SERVER['REQUEST_URI'];
}
}
