Sometimes you get error messages like the following if you try to handle huge amount of rdf graphs.

  .rbenv/versions/1.9.3-p194/lib/ruby/gems/1.9.1/gems/addressable-2.2.8/lib/addressable/uri.rb:1319: [BUG] Segmentation fault

Make sure you are using at least version 0.3.8 of rdf gem (`bundle install` again):

Gemfile.lock

    rdf (0.3.8)
