Hm... it seems I was wrong. gnome-vfs *does* use FD.o MIME sniffing.
However, my problem is still not solved. I have two entries in 
$XDG_DATA_DIRS: /opt/gnome2/share:/home/hongli/.local/share

I put test.xml in ~/.local/share/mime/packages and ran 
update-mime-database. gnome-vfs looks in /opt/gnome2/share/mime/magic 
first and sees that image/png matches the file, and stops there, even 
though ~/.local/share/mime/packages/test.xml has a higher matching priority.
If I put test.xml in /opt/gnome2/share/mime/packages, then it works. 
Unfortunately I can't make my app to do that because it requires root 
permissions.

I think gnome-vfs should look in *all* dirs in XDG_DATA_DIRS and see 
which magic entry contains the highest priority.
