Same problem in a MacBook2,1 with brazilian special characters unavailable.
mabovo@macbook:~$ xprop -root | grep XKB
_XKB_RULES_NAMES_BACKUP(STRING) = "xorg", "apple_laptop", "us", "basic", "grp_led:scrol l,compose:rwin,lv3:lwin_switch,grp:alts_toggle"

mabovo@macbook:~$ gconftool-2 -R /desktop/gnome/peripherals/keyboard/kbd
 layouts = [us basic]
 model = apple_laptop

It seems that problem has gone after today updates:

mabovo@proliant400:~$ xprop -root | grep XKB
_XKB_RULES_NAMES_BACKUP(STRING) = "xorg", "pc105", "br", "", ""
_XKB_RULES_NAMES(STRING) = "xorg", "pc105", "us", "", "compose:ralt,grp:alts_toggle"
mabovo@proliant400:~$ gconftool-2 -R /desktop/gnome/peripherals/keyboard/kbd
 layouts = [us]
 model = pc105
 options = [Compose key compose:ralt,grp grp:alts_toggle]
 overrideSettings = true

mabovo@macbook:~$ xprop -root | grep XKB
_XKB_RULES_NAMES_BACKUP(STRING) = "xorg", "apple_laptop", "us", "basic", "grp_led:scrol l,compose:rwin,lv3:lwin_switch,grp:alts_toggle"
_XKB_RULES_NAMES(STRING) = "xorg", "apple_laptop", "us", "basic", "grp_led:scrol l,compose:rwin,lv3:lwin_switch,grp:alts_toggle"
mabovo@macbook:~$ gconftool-2 -R /desktop/gnome/peripherals/keyboard/kbd
 layouts = [us basic]
 model = apple_laptop
 options = [grp_led grp_led:scrol l,Compose key compose:rwin,lv3 lv3:lwin_switch,grp grp:alts_toggle]
