I think that there are problems on both sides of this. On the Ruby side, it makes a lot of sense to have Rails be part of the testing process, simply because it is such a prominent Ruby application framework. This doesn't mean that the Ruby people need to fix Rails, just that they should be aware when a core update breaks it. On the Rails side, a bit more understanding, and a willingness to jump in and help, would go a long way.
