I am having the same problem with Rails 3.0.3. If you don't require context-dependent labels, you can use en.activerecord.attributes.activity.some_field_here (notice it is not nested inside the person model). However, I have not found any workaround if your label IS context dependent, and I believe it should probably be filed on lighthouse.
