After installing Ubuntu 7.04 I get an "Error activating XKB configuration." error message

After upgrading from 6.10 to 7.04 I get this error message on every reboot or trying to change access the keyboard preferences:
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
70200000

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

Here are the results:
david@hardin:~$ xprop -root | grep XKB
_XKB_RULES_NAMES_BACKUP(STRING) = "xorg", "pc105", "us", "", "lv3:ralt_switch"
_XKB_RULES_NAMES(STRING) = "xorg", "pc105", "us", "", "lv3:ralt_switch"
david@hardin:~$ gconftool-2 -R /desktop/gnome/peripherals/keyboard/kbd
