Will this change in the future? In my opinion it is unacceptable to 
expect users to restart Nautilus every time an app has installed a new 
MIME type.

To be more specific: gnome-vfs "prefers" to use 
/etc/gnome-vfs-mime-magic. I have a MIME file that looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info";>
  <mime-type type="application/x-mytest">
    <comment>Testing MIME override</comment>
    <magic priority="51">
      <match type="string" value="\x89PNG" offset="0"/>
    </magic>
    <glob pattern="*.png"/>
  </mime-type>
</mime-info>

I put this in ~/.local/share/mime/packages, run update-mime-database 
~/.local/share/mime and restart Nautilus. Nautilus detects *.png files 
are application/x-mytest... until you click on them. Then they change 
back to image/png.

I fiddled with the priority number but there is *no way* to override 
gnome-vfs-mime-magic.
