Oh, it's not the editor. I can copy my (now protected) .gvimrc to 
another directory and, as soon as I rename it to gvimrc it "becomes" an 
HTML mime type. If I then rename it to gvimrc.txt, then it becomes a 
text/plain type again.

Try it. Create an empty text file called fred. Add some text and it will 
behave as a regular text file. Now, add the lines:

<script>
<script>

save it, and it's changed to an HTML file type. You can use any editor 
to do this. (If you only use one line containing <script>, then the type 
doesn't change. It knows what it's looking for :-) )

I thought that it might be associated with Desktop/Behaviour/File 
icons/Show icon previews, but I switched them off for text and HTML 
files and it still happens.

What is parsing files to cause this? I want it to stop!
