Hello,

I can confirm that gnome-control-center removes XKBMODEL from 
/etc/default/keyboard.  Steps to reproduce:

1. $ grep -q XKBMODEL /etc/default/keyboard && echo fine || echo broken
   -> fine
2. $ gnome-control-center
3. Go to "Region & Language"
4. Go to "Login Screen"
5. In the "Input Sources" section add some random keyboard layout
6. $ grep -q XKBMODEL /etc/default/keyboard && echo fine || echo broken
   -> broken

The test is done on a regular Jessie system.  The version of gnome-control-center 
is 1:3.14.2-3.

By the way, I was very surprised to find that gnome-control-center modifies a 
configuration file belonging to other package.  This is not something Debian 
policy permits.  Nevertheless, we do want the keyboard configuration to be user 
friendly, so I approve what gnome-control-center does, as long as it does it 
correctly. :)

By the way, I've found that gnome-control-centers doesn't remove the variables it 
doesn't understand.  Therefore, it seems the reason it removes XKBOPTIONS and 
XKBMODEL is that it tries to do something with these variables.
