Comment 22 for bug 1013881

Ok, checking on lucid, by then we had this fix:
http://launchpadlibrarian.net/44180279/xkeyboard-config_1.8-1ubuntu6_1.8-1ubuntu7.diff.gz

"# Description: Don't include level4nl but only level4n for french oss layout.
# both space and Ctrl + space returned the same XLookupString, which prevents
# space using in some application using gtk_action_group_add_toggle_actions
# to setup Ctrl + space accelerator. We loose rctrl accelator but that's better
# than not having space in those applications and setup it manually will
# reintroduce https://bugs.launchpad.net/bugs/198759

so by then we didn't add the "include "level5(rctrl_switch)"" line ... does anyone know why it was added this time? it seems lucid in fact had both rhythmbox and rctrl working
