The current "work-around" I have found is to do file-type checking
within the script, using the 'file' command. "file -i <filename>" will
return a mime-type and  "file <filename>" a more human-readable
description.  That way, at least you can prevent the script from
processing the wrong type of file.  Its doesn't make the scripts
disappear from the scripts menu when they aren't relevant, but I don't
know if that is as useful as one might think.  For instance, suppose you
have a script that processes text files of any kind (source code, html,
text documents, etc.), but you don't want it to process binary files
(pictures, zip files, executables, etc.)  It is not a simple task to
designate which file types you want and which you don't. Which,
apparently, is why I had to change a half-dozen entries in the mime
database when I wanted to use garchiver instead of guitar.


Example usage of "file" can be found at:

Specifically: 

script to display mimetype:

script to display filetype:

omnibus printing script that checks for file type and prints the file it
if it knows how to:
