Bug#397945: File type detection is broken and annoying ("cannot open FOO")

[Anthony DeRobertis]

Package: nautilus
Version: 2.14.3-3
Severity: normal

Routinely I get dialogs that read along the lines of:

    Cannot open FOO.js

    The filename "FOO.js" indicates that this file is of type
    "JavaScript program". The contents of the file indicate that the
    file is of type "C source code". If you open this file, the file
    might present a security risk to your system.

    Do not open the file unless you created the file yourself, or
    received the file from a trusted source. To open the file,
    rename the file to the correct extension for "C source code",
    then open the file normally. Alternatively, use the Open With
    menu to choose a specific application for the file.

This is not the most absurd one I've gotten. Once it decided that a WAV
file — that's right, a binary file — is plain text! And then refused to
play it...

1. This file doesn't look like C code, at least not any more than any
   other JavaScript code. Currently, it is available on the web at 
   <http://asurvey.net/ccsfagent/media/survey.js>.

2. It might present a security risk to the system about as much as, say,
   a meteor. A meteor could hit the system. A C file named FOO.js is
   probably no more likely to present a security risk when passed to
   gvim.

3. The suggestion to rename it is, of course, silly because it's been
   misidentified.
   
4. The suggestion to use Open With is silly because you have to do that
   each and every time; there is no way to say "no, you idiotic
   nautilus, you're wrong, it's a damned javascript file, shut up."

I've searched preferences, I've searched gtweakui-nautilus, I've
searched gconf: There appears to be no way to turn off this. Please,
please fix it...
