Description:
------------
When I write some RewriteRule with additional "redirected" variables, they seem to be empty in my script.

RewriteRule ([a-z]+/)?([0-9]+) job_view.php?job_sid=$2&theme=$1

When I call the following URL "http://localhost/gray/56", I expect in my script to have these variables:

job_sid => string(2) "56"
theme => string(4) "gray"

But what var_dump($job_sid) and var_dump($theme) actually tells me is:

job_sid => string(2) "56"
theme => string(0) ""

Note that $theme is an empty string, but not null.

The weirdest thing is that var_dump($_GET) shows correct result:

array(2) {
  ["job_sid"]=>
  string(2) "56"
  ["theme"]=>
  string(4) "gray"
}

I forgot to mention, that I have register_globals=On, so I expect ALL of my $_GET variables to be registered as globals.

Reproduce code:
---------------
var_dump($_GET);
var_dump($job_sid);
var_dump($theme);

Expected result:
----------------
array(2) {
  ["job_sid"]=>
  string(2) "56"
  ["theme"]=>
  string(4) "gray"
}
string(2) "56"
string(4) "gray"

Actual result:
--------------
array(2) {
  ["job_sid"]=>
  string(2) "56"
  ["theme"]=>
  string(4) "gray"
}
string(2) "56"
string(0) ""
