Do you need the solution? ;)

Apparently the Rails 3.1.0.beta1 requires pull in Sprockets 2.0.0.beta.3 which has issues. Forcing it to use Sprockets 2.0.0.beta.1 solves the issue. Alternatively, switching to Rails master also solves it.

Didn't know these were searchable... :)

Indeed, that's what I had to do too.

Sorry for having generated noise :)
