keyboard configuration doesn't works after SID upgrade

[Csanyi Pal <csanyipal@gmail.com>]

Hi,

my system is Debian GNU/Linux unstable (sid).

In the file /etc/default/keyboard the followings setup is present:
XKBMODEL="pc105"
XKBLAYOUT="hu,hr,rs"
XKBVARIANT="nodeadkeys"
XKBOPTIONS="grp:rwin_toggle,terminate:ctrl_alt_bksp,grp_led:scroll"

BACKSPACE="guess"

This setup works sofar, but today suddenly stop working, after I upgrade
my SID system.

How can I solve this problem?
Is this a bug? If yes, in which package is the bug?
