Bug#859268: debian-installer: French keyboard selected during install but QWERTY selected when logged in Gnome

[Cyril Brulebois]

Control: severity -1 important

This really should be fixed ASAP, and also in stretch.

gdm3 seems to be just fine (tried to type a user name there, and I was
getting the default French layout there), so I've looked into gnome-shell,
which seems to toy with XkbInfo, exposed by libgnome-desktop. Looking at
libgnome-desktop/gnome-xkb-info.c in src:gnome-desktop3, what you mentioned
about the variant changing things might be connected to this part of the
add_layout_to_locale_tables() function:
|   lang_codes = layout->iso639Ids;
|   country_codes = layout->iso3166Ids;
| 
|   if (layout->is_variant)
|     {
|       if (!lang_codes)
|         lang_codes = layout->main_layout->iso639Ids;
|       if (!country_codes)
|         country_codes = layout->main_layout->iso3166Ids;
|     }

So depending on the is_variant flag, we get overriden values for
{lang,country}_codes, looking at a layout->main_layout instead of just
layout? I haven't double checked this by inserting some gdb or print
statements though.
