it fails for shared strings if begin != 0

require 'base64'

@ahorek thanks for this fix. I noticed right before rubyconf something was not properly decoding CSRF tags but when I quickly looked we were decoding properly (which of course was because my new string was not shared and begin == 0). The number of times this lack of abstract has hurt us is a bloody affair.
