/Library/Ruby/Gems/1.8/gems/scrubyt-0.2.0/lib/scrubyt/extractor.rb:143:in `+’: can’t convert nil into String (TypeError) from /Library/Ruby/Gems/1.8/gems/scrubyt-0.2.0/lib/scrubyt/extractor.rb:143:in `fetch’ from /Library/Ruby/Gems/1.8/gems/scrubyt-0.2.0/lib/scrubyt/extractor.rb:214:in `click_link’ from publicvista.rb:7 from /Library/Ruby/Gems/1.8/gems/scrubyt-0.2.0/lib/scrubyt/extractor.rb:30:in `class_eval’ from /Library/Ruby/Gems/1.8/gems/scrubyt-0.2.0/lib/scrubyt/extractor.rb:30:in `define’ from publicvista.rb:4
