更新： 现在错误也发生在dev上。在应用程序中有图像缓存。错误导致一种方法：
def f_respond_to (merge_result,fieldable)
respond_to do |format|
format.html
format.png do
i = ImageCaching.new
updated_at = get_updated_at(fieldable)
att = i.find_or_destroy_by_uri(request.path,updated_at)
if(att == nil)
att = create_new_image(i, merge_result)
end
render :text=>i.read(att.uri), :content_type=>att.content_type
end
format.pdf do
redirect_to download_pdf_path(:key=>fieldable.key)
end
end
