Bug#183406: kbd-chooser: setfaults if default answers is preloaded into debconf

[Petter Reinholdtsen <pere@hungry.com>]

Package: kbd-chooser
Version: 0.010
Severity: important

I got a udeb (skolelinux-config-udeb) loading some default values into
debconf to get the installation to continue automatically.  This
package does the following in it's postinst script:

  #! /bin/sh
  . /usr/share/debconf/confmodule
  [...]
  layout="[no-latin1] Norwegian"
  [...]
  db_set console-data/keymap/ps2 "$layout"

When this is executed before kbd-chooser is executed, kbd-chooser
segfaults at startup.

If I choose kbd-chooser from the menu before installing
skolelinux-config-uden, it works just fine.  But if I execute it after
the configuration is loaded, it crashes.
