Comment # 6 on bug 1040272 from Oliver Kurz

Testing again while changing only the installer keyboard layout, not the
language. I selected plasma this time as the DE but that should not matter.
Now, within the installed system, selecting the yast gui module "system
keyboard layout" is pre-selected as german. So I suspect that either the
"keyboard layout" vs. "language" selection makes a difference or my report is
invalid because I might have tested a very old, outdated leap 12.3 (from
dist.suse.de).

I will check again an installation where I change "language".
