I18n Transliteration in apache with canvas

I’m using Apache with canvas and Ruby but I cannot start apache. It shows that “Could not spawn process for application /var/canvas: The application encountered the following error: Transliteration rule must be a proc or a hash. (I18n::ArgumentError) Error ID: 99b4a81e Error details saved to: /tmp/passenger-error-vzBKfy.html”. How can I solve it? I tried search the problem in the internet but I cannot find a solution. Thanks.
