Avoid "Foodsoft Error" for unknown URLs

[paroga]

I regularly get the following error because some user want to access an not existing file "/apple-touch-icon.png":

An ActionView::MissingTemplate occurred in home#index:

  Missing template home/index, application/index with {:locale=>[:de, :en], :formats=>[:png], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :haml]}. Searched in:

Good point. I guess we could setup a default logo image? Perhaps we could improve on our current :)

For me it would be already ok if we could serve a simple 404 and don't raise an error. :-)

Hmm, I guess I missed the point ;) Let's do that, I'll have a look.

Some options:

• http://jerodsanto.net/2014/06/a-step-by-step-guide-to-bulletproof-404s-on-rails/
• https://gist.github.com/gonzedge/1563416

• https://github.com/eric1234/better_exception_app

I'm experimenting with Gaffe and it seems to work quite well.

PR in #375, would that solve your issue?

Should be fixed with #375, please reopen when this is still a problem.
