SystemStackError (stack level too deep) при совместной работе с плангином clipboard_image_paste

[pragmaton]

Для простоты свел условия к минимум.
Чистый Redmine 2.6.1
Устанавливаем ваш плагин и https://github.com/peclik/clipboard_image_paste В котором так же есть патч Issue

Пытаемся отредактировать любое поле тикета. При сохранение получаем Internal error
если смотреть в дев консоль, то видим

Completed 500 Internal Server Error in 110.2ms
SystemStackError (stack level too deep):
  actionpack (3.2.21) lib/action_dispatch/middleware/reloader.rb:70

К сожалению, я не очень силен рельсах и redmine. Как мне кажется проблема связана с тем что патч подгружается несколько раз, не смотря на вашу проверку.
Моих навыков не хватило, что бы глубоко понять проблему, но на базе http://stackoverflow.com/a/11295999 сделал патч, который вроде как решает проблему. Но мне кажется он кривоват...
