I'd say you should never change permissions and ownerships unless you  
really understand what you're doing, I like to err on the safe side.

Besides, both users are allowed to copy the file to the desktop,  
right? As far as I can see, the ownership situation is symmetrical.

Can you see which temporary directory is used for either user? Does  
texshop / simpdftex use the designated temporary directory (/tmp/ 
$UID) or does it work in /tmp? I assume that the issue didn't start  
until the second user tried to open the file. Can the user that can  
open the file remove the temporary files, and give the other user a  
try at opening the file? If that works, can the first user still open  
the file?

I tried the same file, and TeXShop or simpdftex creates a directory  
in the /tmp/ dir with the name TeXShop_Output, only writable to the  
user that started TeXShop:
     drwxr-xr-x    2 maarten   wheel      68 Jan  1 23:23 TeXShop_Output

The second user cannot create this directory, and opening a dvi file  
from a read only location fails. TeXShop should either clean up after  
itself, or use the users level sub-dir in /tmp (i.e. /tmp/$UID).

I think it isn't an issue with permissions on your system, but a bug  
or small issue in TeXShop.

PS. Happy new year, to all of you, and especially Richard, who just  
received the first(?) bug report of the new year. Cheers ;-)
