I recently upgraded an application using the new split rails 2.3.5-1, and gettext for translations, so i installed this package to get rails translated. The app complained about missing methods, and after looking at the problem, i found libi18n-ruby1.8 provides a Locale class in the I18n namespace, and liblocale-rails-ruby1.8 is also in this namespace when it calls the Locale class, but it is requiring 'locale' in '/usr/lib/ruby/1.8/locale_rails.rb', so the Locale class wanted is not I18n::Locale but ::Locale provided by liblocale-ruby1.8 (and the wanted methods match). The following patch fixes this issue, even if the use of the I18n namespace should probably be sorted out.
