problem with XKB in xubuntu

[Foxy]

I have a strange problem with xfce. I am trying to make keyboard 
switcher work and so far no avail. The problem seems to be with xkb 
though I am not sure.

The thing is if I log into Gnome I have the following:

> ~$ xprop -root | grep XKB _XKB_RULES_NAMES(STRING) = "base", "pc101", 
> "gb,ru", ",winkeys", "grp:ctrl_shift_toggle"
> _XKB_RULES_NAMES_BACKUP(STRING) = "base", "pc101", "us", "", ""

So I can for example do:

> ~$ setxkbmap -layout 'gb,ru(winkeys)' -option "grp:ctrl_shift_toggle"

to set my keyboard layouts manually. However, if I try the same thing in 
xfce session, I've got the following
> xprop -root | grep XKB
gives me nothing and

> :~$ setxkbmap -layout 'gb,ru(winkeys)' -option "grp:ctrl_shift_toggle"
> Couldn't interpret _XKB_RULES_NAMES property
> Use defaults: rules - 'xorg' model - 'pc101' layout - 'us'
> Segmentation fault

It looks like Gnome loads something that xfce does not or my xfce 
installation is screwed up in some way. Also if I log into xfce after 
logging into Gnome, everything works fine.

Please note that I am using XGL/Compiz with NVidia card. This problem 
does not exists with plain Xorg.

Any help would be appreciated.
