Redirection fails when trying to open remote content using RestClient

[fbacall]

I recently encountered the following error when trying to parse some JSON-LD:
FATAL Failed to parse input document: loading remote context failed: http://schema.org/: Called from /home/finn/.rvm/gems/ruby-2.2.2@tess-scrapers/gems/json-ld-2.1.0/lib/json/ld/reader.rb:63

after doing some digging, I found that it is actually caused by:

ArgumentError: wrong number of arguments (2 for 0)
/home/finn/.rvm/gems/ruby-2.2.2@tess-scrapers/gems/rest-client-2.0.0/lib/restclient/abstract_response.rb:118:in `follow_redirection'
/home/finn/.rvm/gems/ruby-2.2.2@tess-scrapers/gems/rdf-2.1.0/lib/rdf/util/file.rb:112:in `block in open_url'

which is caused by the following line: https://github.com/ruby-rdf/rdf/blob/develop/lib/rdf/util/file.rb#L100

where the RestClient method actually expects a block: https://github.com/rest-client/rest-client/blob/master/lib/restclient/abstract_response.rb#L118

I'm using the latest stable versions of both gems: ruby-rdf (2.1.0) and rest-client (2.0.0)
