Ruby Sesame method calling

Some public methods are working like count() and some I get "freeze" error

gem 'rdf', '=0.3.11.1' require 'rdf' require 'rdf/sesame' require 'rdf/ntriples'

url = RDF::URI("http://localhost:8080/openrdf-sesame")
conn = RDF::Sesame::Connection.open(url)

#server.each_repository do |repository|
#  puts repository.inspect
#end

    repo = RDF::Sesame::Repository.new("http://localhost:8080/openrdf-sesame/repositories/TEST")
   repo.clear_statements() # does not work
   puts repo.count() # gives the number of statements in the repository

May someone has a hint as I am not familiar with ruby programming.

Part of the error message: (the other error I get is the NoMethodError which comes from wrong usage of protected methods I guess)

/home/USER/.rvm/gems/ruby-2.1.2/gems/addressable-2.3.6/lib/addressable/uri.rb:1658:in `normalized_fragment': can't modify frozen Addressable::URI (RuntimeError)
    from /home/USER/.rvm/gems/ruby-2.1.2/gems/addressable-2.3.6/lib/addressable/uri.rb:823:in `freeze'
    from /home/USER/.rvm/gems/ruby-2.1.2/gems/rdf-0.3.11.1/lib/rdf/model/uri.rb:475:in `freeze'

The problem is caused through a newer version of addressable!

When I add in the header:

gem 'addressable', '~> 2.2.6'
require 'addressable/uri'

I don't get the Error anymore! Version 2.2.6 or newer is required for rdf-sesame!
