In order to debug javascript in my heroku production environment, I need to disable asset compression (or at least compression of javascript). I tried config.assets.c
Looks like this MAY have been a bug in Rails. From the changelog for upcoming rails 3.2.9, is this what you were running into?
Respect config.digest = false for asset_path
Previously, the asset_path internals only respected the :digest option, but ignored the global config setting. This meant that config.digest = false could not be used in conjunction with config.compile = false this corrects the behavior.

Do you think that could be related?
