Removing an individual plgin association in Mozilla (not the entire plugin)
 

Basically I am wanting to remove the real player file association in mozilla with xine. Everytime i try to download an RPM file, it associates it as a Real file...thus opening Xine. I like Xine a lot and the file associations within mozilla (remove the Xine splash screen and it's very nicely built in with mozilla on my machine).

But I can see the exact file i need to change, but i need to know what to do! Is there a simple KDE setting i could change or do i need to change the file itself? Steps would be nice for me ;)
