Issue with ie7 about elusive-icons-sass-rails HOT 2 CLOSED

http://stackoverflow.com/questions/16669991/most-of-my-assets-suddenly-return-404-after-a-push-to-heroku

# Do not fallback to assets pipeline if a precompiled asset is missed.
config.assets.compile = true

But this is a very suboptimal solution, as it makes the app slow.
But ie7 icons are still not precompling

Old issue, irrelevant since IE 7 is deprecated.
