Preseeding german keyboard layout in Wheezy

[Bernhard Schmidt <berni@birkenwald.de>]

Hi,

I'm currently trying to streamline our Debian deployment using
preseeding and I'm having issues setting a German keyboard layout. I use
Wheezy daily 20121114 at the moment.

Goals:
- installer should be English
- the country should be set to Germany (so timezone is okay)
- default locale of the installed system should be English (so program
  messages are not translated)
- the keyboard should be set to German layout

I can successfully set that configuration using a full manual
installation but I seem to be missing some setting when using preseed
commands.

I use the following boot options:
debian-installer/language=en debian-installer/country=DE
debian-installer/locale=en_US.UTF-8 keymap=de

The keymap question is not asked anymore (it is when I remove setting
keymap=), but the keymap is still English. I also tried
keyboard-configuration/xkb-keymap=de without success

Any ideas what I'm doing wrong? I've seen Bug #693493 but I'm already
using the new option, so I'm at a loss here.
