URI.decode_www_form pukes out an ArgumentError if passed any parameter names that aren't followed by an equals sign. Because of this it can't decode some of the strings that were encoded with URI.encode_www_form:

irb> require 'uri'
=> true
irb> querystring = URI.encode_www_form 'a' => '1', 'b' => nil
=> "a=1&b"
irb> URI.decode_www_form querystring
ArgumentError: invalid data of application/x-www-form-urlencoded (a=1&b)
from /Users/misfo/.rbenv/versions/2.0.0-p0/lib/ruby/2.0.0/uri/common.rb:975:in decode_www_form' from (irb):3 from /Users/misfo/.rbenv/versions/2.0.0-p0/bin/irb:12:in '

• lib/uri/common.rb (URI.decode_www_form): follow current URL Standard.
  It gets encoding argument to specify the character encoding.
  It now allows loose percent encoded strings, but denies ;-separator.

• lib/uri/common.rb (URI.decode_www_form): follow current URL Standard.
  It gets encoding argument to convert before percent encode.
  Now UTF-16 strings aren't converted to UTF-8 before percent encode
  by default.
