How can I remove the "Media files" banners in Nautilus?

[Bob Jonkman]

Whenever I plug my Android into my laptop I get two dialogue boxes "This 
drive contains pictures/music, do you want to open Shotwell/Rhythmbox?". 
   Then when I open Nautilus there are two banners across the top of the 
file list that read "Open Shotwell Photo Manager; the media contains 
digital photos" and "Open Rhythmbox Music Player; these files are on a 
digital music player".

I can get rid of the initial dialogue boxes.  But how do I get rid of 
the two banners across Nautilus?  There are no "Close" buttons, and I 
have found nothing in the menus.  Those banners just take up far too 
much vertical screen space, so I want them gone.
