coping a file after uploading does work?

Hi, I'm perforrming an HTTP upload to the tmp directory of the system. I am sure this works cause, I can do anything with this file, except copy it to a new location (yes writable for php), rename it or delete it. The function move_uploaded_file() or copy_uploaded_file() crashes PHP 4.0.2 (it is not supposed to work yet, but a crash?)
