Xorg 7.3: setxkbmap gives error "Error loading new keyboard description"

[Markus Strobl]

Since I went to Xorg 7.3 I can no longer switch my keyboard layout.
The KDE layout icon shows "err" and the setxkbmap command gives me:


markus at markuspc ~ $ setxkbmap -model pc104 -layout us
Error loading new keyboard description

I spent a few hours searching the net and couldn't find a fix???

Thanks,
Markus
