Comment 28 for bug 548631

I experience this bug as well (Lenovo 3000 N200, fairly clean install of xubuntu lucid — but I see new versions have the same thing, xfce-xkb-plugin 0.5.3.3-1ubuntu3).

My .config/xfce4/panel/xkb-plugin-13220036240.rc (although the number is large, this is the only xkb-plugin-*.rc that is, or ever has been present there) looks like this (as intended) even after logout:

display_type=1
group_policy=0
default_group=0
never_modify_config=false
model=pc105
layouts=pl,ru
variants=,phonetic
toggle_option=grp:shifts_toggle
compose_key_position=compose:menu

Nevertheless, in the plugin itself the toggle and compose dropdowns are both set to "-" and neither keystroke (Shifts toggle, Compose on Menu) works. I attach my .xsession-errors; it contains the following line thrice:

(xfce4-xkb-plugin:6032): GLib-CRITICAL **: g_hash_table_destroy: assertion `hash_table != NULL' failed

I sure hope that helps, as xubuntu is my last resort in the *ubuntu world after I have experienced the horrors of Unity/GNOME 3 when upgraded my Ubuntu to natty and oneiric.
