FileNotFound for gold-cc-cvc-input when precompiling

[rexfng]

There's a problem when I precompile my files for production.

I, [2015-11-09T20:30:43.997980 #11889]  INFO -- : Writing /Users/app/

Sprockets::FileNotFound: couldn't find file '' with type 'text/html'

gem 'polymer-rails', github: 'alchapone/polymer-rails'
gem 'polymer-elements-rails', github: 'alchapone/polymer-elements-rails'

This fixed it for me

@cedbonhomme Your solution worked for me too, but I'm curious why. Is the version in rubygems behind the version in github? That must be the case, but based on the dates it doesn't seem like it.
