undefined method keys' + undefined method clear_tags!'

Hi,

I'm using grape inside Rails. When using Rails.logger as logger and GrapeLogging::Formatters::Default as formatter, I receive these exceptions ( complete backtrace ) when grape tries to log the request.

This is my configuration:

module Foobar
  class Api < Grape::API
    logger Rails.logger

    use GrapeLogging::Middleware::RequestLogger,
      logger: logger,
      formatter: GrapeLogging::Formatters::Default.new,
      include: [ GrapeLogging::Loggers::Response.new,
                 GrapeLogging::Loggers::FilterParameters.new,
                 GrapeLogging::Loggers::ClientEnv.new,
                 GrapeLogging::Loggers::RequestHeaders.new ]

I noticed that if I change logger Rails.logger with logger Rails.logger.dup it works, without any exception. Why?
