138               "\n\n#{exception.class} (#{exception.message}):\n    " +
139               clean_backtrace(exception).join("\n    ") +
140               "\n\n"
141             )

248       def clean_backtrace(exception)
249         if backtrace = exception.backtrace
250           if defined?(RAILS_ROOT)
251             backtrace.map { |line| line.sub RAILS_ROOT, '' }
252           else
253             backtrace
254           end
255         end
256       end
