Redmine

Hi!

I just realized, that I have really bad problems with CodeRay syntax highlightning..
I've got installed CodeRay 1.0.9 and didn't modify the "../lib/redmine/syntax_highlighting.rb"

My production.log says

ActionView::Template::Error (#<Class:Redmine::SyntaxHighlighting>#highlight_by_filename delegated to highlighter.highlight_by_filename, but highlighter is nil: Redmine::SyntaxHighlighting):
    2: <table class="filecontent syntaxhl">
    3: <tbody>
    4: <% line_num = 1 %>
    5: <% syntax_highlight_lines(filename, Redmine::CodesetUtil.to_utf8_by_setting(content)).each do |line| %>
    6:   <tr>
    7:     <th class="line-num" id="L<%= line_num %>">
    8:       <a href="#L<%= line_num %>"><%= line_num %></a>
  lib/redmine/syntax_highlighting.rb:26:in `highlight_by_filename'
  app/helpers/application_helper.rb:386:in `syntax_highlight'

  app/views/repositories/entry.html.erb:11:in `_app_views_repositories_entry_html_erb__357234730_69905589081340'

Could anybody help me please?
This really takes me down :(
