Root cause is that snippets is an array.but

    a=["hugo"];b="foobar/#{a}"

yields

   1.8.7: "foobar/hugo"
   1.9.3: "foobar[\"hugo\"]" 

Problem ocurs in line 246 of class.proolib.rb

    if snippets.nil?
        @snippets       = nil 
    else
        @snippets       = File.expand_path("#{basePath}/#{snippets}")
    end
