Reproduce the reported commands on Debian Jessie with the shown de_DE.UTF-8 locale, then trace the locale-handling path involved in startup. The issue does not provide expected or actual output, so first establish the failure; done means logkeys starts successfully without requiring a different LC_CTYPE locale.
