It's probably important to backport #4918 to Rails 3.2 stable.

backporting #4918 to 3.2 stable; adding extra test for accept header …

Awesome. Thanks for this guys. @josevalim are there still going to be maintenance/security releases of 3-0 and 3-1 branches? I know some people that would appreciate this fix there as well. If that's a reality, I'd be happy to help put that pull request together.
There will be security fixes for 3.1, but security fixes are usually from the latest tag to avoid including regressions. So there isn't a need to backport.
