Error activating XKB configuration

When enabling in keybord configuration anything different from settings in xorg.conf, I get this message in Hardy (fully updated):

Error activating XKB configuration.
It can happen under various circumstances:
- a bug in libxklavier library
- a bug in X server (xkbcomp, xmodmap utilities)
- X server with incompatible libxkbfile implementation

X server version data:
The X.Org Foundation
10400090

If you report this situation as a bug, please include:
- The result of xprop -root | grep XKB
- The result of gconftool-2 -R /desktop/gnome/peripherals/keyboard/kbd

$ xprop -root | grep XKB
_XKB_RULES_NAMES_BACKUP(STRING) = "xorg", "pc105", "us,cz", ",qwerty", ""
_XKB_RULES_NAMES(STRING) = "xorg", "pc105", "us,cz", ",qwerty", ""

$ gconftool-2 -R /desktop/gnome/peripherals/keyboard/kbd
 layouts = [us qwerty,cz qwerty]
