Bug#528033: console-setup: config file does not contain "bepo" variant selected in debconf

[Raphaël Hertzog <hertzog@debian.org>]

Package: console-setup
Version: 1.34
Severity: important

I do use the french layout with the "bepo" variant. I used to have:
XKBMODEL="pc105"
XKBLAYOUT="fr"
XKBVARIANT="bepo"

After upgrade I lost those settings (see #527641, already reported)
and discovered that this file is overwritten by the debconf configuration.
So I decided to update the debconf configuration with dpkg-reconfigure
console-setup and selected the variant that I wanted (France - Bepo
ergonomic Dvorak way) but it turns out that this selection ends up
with:
XKBLAYOUT="fr"
XKBVARIANT=""

Which is clearly not what I expected.
