Commit 70e339b86b0d4a000e0e62253703ac4ca8618b74 introduced the bug
resulting in almost empty dictionary of country layout variants.
Iteration over countries uses the same _get_variant method as iteration
over languages, but comes afterwards. The check added in
70e339b86b0d4a000e0e62253703ac4ca8618b74 fails for almost every layout
that is processed in iteration over countries.
I think this one is alright.
