I am using google-webfonts-rails gem w Rails 4.1.6 / Bootstrap 3.1 ( don't know if it's a good choice...)
I tried to get rid of this error by adding fonts folders w glyph icons in many places ...
app/assets/fonts/...
app/assets/javascripts/fonts/...
app/assets/stylesheets/fonts/...
and I still get this error in the console log :
Started GET "/fonts/glyphicons-halflings-regular.ttf" for 127.0.0.1 at 2014-10-08 11:11:59 +0200
Processing by ApplicationController#routing_error as
Parameters: {"path"=>"fonts/glyphicons-halflings-regular"}
Completed 404 Not Found in 7ms
it's still not very clear to me where I should add the fonts w Bootstrap3 ....
