Comment 16 for bug 7848

Selecting Keyboard Preferences/Layouts/Hungarian and Add I got the following
error:

Error activating XKB configuration.
Probably internal X server problem.

X server version data:
The XFree86 Project, Inc
40300001
You are using XFree 4.3.0.
There are known problems with complex XKB configurations.
Try using simpler configuration or taking more fresh version of XFree
software.
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/xkb

And here are the results:
$ xprop -root| grep XKB
_XKB_RULES_NAMES_BACKUP(STRING) = "xfree86", "pc104", "fi", "", ""
_XKB_RULES_NAMES(STRING) = "xfree86", "pc104", "fi", "", "grp:alts_toggle"
$ gconftool-2 -R /desktop/gnome/peripherals/keyboard/xkb
 layouts = [fi,hu]
 model = pc104
 overrideSettings = false
 options = [grp grp:alts_toggle]
 update_handlers = []

Tried many layouts and its seems than only with the "Hungarian" layout is
some problem.
