Ruby on rails Google favicon爬虫导致Rails 3.2上的ActionView:：MissingTemplate异常

每次Google Favicon crawler试图获取仅接受

图像/*

格式的根url时，我都会遇到

ActionView:：MissingTemplate

异常

爬网程序用户代理是：

Mozilla/5.0（Windows NT 6.1；rv:6.0）Gecko/20110814 Firefox/6.0 Google Favicon

我可以使用以下命令重现此异常：

curl-v-H“接受：图像/*”http://localhost:3000

我正在使用一个名为omega的自定义布局（在

/layouts/omega

路径上），这会影响这样的框架吗

这不是一种不当行为吗

我怎样才能解决这个问题并为favicon服务

错误日志：
