Redmine

I'm running in this reproducable test fail with Version redmine-3.3.2.tar.gz (md5: 8e403981dc3a19a42ee978f055be62ca)
This test doesn't fail with redmine-3.3.0

  1) Error:
Redmine::I18nTest#test_languages_options_should_ignore_locales_without_general_lang_name_key:
I18n::InvalidLocale: "foo" is not a valid locale
    lib/redmine/i18n.rb:58:in `ll'
    lib/redmine/i18n.rb:110:in `block in languages_options'
    lib/redmine/i18n.rb:110:in `map'
    lib/redmine/i18n.rb:110:in `languages_options'
    test/unit/lib/redmine/i18n_test.rb:203:in `test_languages_options_should_ignore_locales_without_general_lang_name_key'

I suspect it has something to do with the rails update from 3.3.0 (rails 4.2.6) and 3.3.2 (rails 4.2.7.1)
