Comment 11 for bug 829470

No, there seems to be more to it than that.

And in a freshly upgraded chroot:

I think the empty /var/lib/xkb/ may be a symptom rather than a root cause. Guessing that in the buildd's there's no keyboard so no compiled xkb keymap is going to get generated.

Martin, can you elaborate on how you're reproducing it? Are you doing it in a local chroot or on a buildd?
