(Firefox :: File Handling, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.8.1.14) Gecko/20080404 Firefox/2.0.0.14

Clicking on downloaded exe installer files generates spurious "External Protocol Request" popup making installation impossible. Several people have complained of this on the web.
I think the problem is that mimetypes.rdf contains the line
xmlns:NC="http://home.netscape.com/NC-rdf#" 
This URL no longer exists. So even if this isn't the cause of the download problem, it should be fixed.

Reproducible: Always

Steps to Reproduce:
1.download installer exe (eg from Download.com)
2.click on Open (OK on warning)
3. 
Actual Results:  
External Protocol Request popup
An external application must be launched to handle file: links
...

Expected Results:  
No "application" to launch, so you can't open the exe

Duh

I'm not sure what could be causing this error, but it's unrelated to that URL.  The URL in question is used purely as a namespace and is never contacted directly for any kind of validation.
