No, there's no shebang at the start... it begins with funny special 
characters like umlauts, vocals with acccents... in fact you can take a 
look yourself as the file is publicly available, as it seems.

So maybe the webserver delivers the wrong content type because the magic 
of mime_magic isn't magically enough.
I could of course just exclude any .por and .sav or only include known 
endings; it's just bad if the users only need to put in a file that is 
somehow broken to make the indexer crash... users are evil ;-)
