Description:
------------
When I upload any file which name has space( example. "test test.txt"),it occured system error.
it happened before executing php script,so I couldn't do noghing...

And I think it is a PHP 4.4.0's unique bug.
it never occured at PHP 4.3.6.


The uploaded file is small one ,and has no paticular point except having a name with space.




Reproduce code:
---------------
<?php
if($_POST["sub_btn"]){
  print "send file";
  exit();
}
?>
<!-- HTML -->

<form  enctype="multipart/form-data" method="post" action="qa.php">
<INPUT type="file" size="50" name="image_file1">
<INPUT name="sub_btn" type="submit" value="send file">
</form>



Expected result:
----------------
send file

/*
you must choose the file which name has space(ex. "t e.txt"
After you had submited, it occured system error.
*/



Actual result:
--------------
system error
