Changing your example slightly shows what could be the problem:

class QuestionnaireAnswerError < ArgumentError
attr_accessor :question_id

def initialize(*args)
self.question_id = args.shift
super(args)
end
end

class BadAnswerCountError < QuestionnaireAnswerError
end

class TooManyAnswersError < BadAnswerCountError
end

class TooManyAnswersError < QuestionnaireAnswerError
end

It looks like you've tried to define the class twice with different
super classes.
