Theme doesn’t want to load localization files

One error: the function is load_theme_textdomain(), not load_textdomain(). The former is used for Themes to define/load a textdomain; the latter is for core, I believe. (Plugins have an analogous function, load_plugin_textdomain().)

Try using:

load_theme_textdomain( get_theme_text_domain(), get_template_directory() . '/languages' );
