Leopard: Folder Actions and Safari Downloads

Considering that .download files are packages, it makes sense that the file addition handler is triggered when the download is started and both the file addition and removal handlers would be triggered once Safari has finished downloading, with the addition handler providing the alias to the downloaded file and the removal handler providing a string containing the name of the removed .download folder. While I found that the handlers are triggered as described above, I could not access the alias list being passed to the handler. I tried using try/error block and no errors were reported and I am wondering if there’s a way for me to find out what was being passed to these handlers.
