Thats strange: when I use rvm + bundle install (with our repo), it 
works. When I switch to system ruby and gems (from yum), if falls.

Apparently, there are some differences between gems in our repo, and in 
rpm packages (despite the same versions).

E.g.:

diff 
/usr/lib/ruby/gems/1.8/gems/activesupport-3.0.5/lib/active_support/core_ext/string/output_safety.rb 
~/.rvm/gems/ruby-1.8.7-p352\@katello/gems/activesupport-3.0.5/lib/active_support/core_ext/string/output_safety.rb

<         end
<       EOT
<     end


This might cause the problem, but it needs some investigation.

Quickfix is:

_("Hello %{w}\n").to_str % {:w =>   'World'}
