[horde] IMP - Error on attachment download

  Yeah, same for me. If you're using Firefox, you "THINK" you're just  
seeing a 500 error as it opens in a new tab with no content. However,  
choose "view source" and you'll see it is an authentication issue  
where the "Download" option isn't carrying the authenticated status  
over correctly. At least, I THINK that's what it is saying.

A fatal error has occurred
User is not authenticated.
