It might think its an executable PR3 can be used as postsrcipt extension 
so I'm suprised it's not allowed with what you have


Filetype rules will over-ride filename everytime, filetype is based on 
system " file " where filename I don't beleive uses file in tests and just 
takes your word for it on filename, making filetype a much more sensible 
approach to be the top level guardian.

try :
file /full/path/to/file.pr3
and see what it says it thinks it is
