Deleting content blocks produces error

[tbodnya]

Happens in 4.0.0.rc1
Go to any custom content block's index page, check blocks that you want to delete and click delete. It gives you an error: no routes matches action index and controller "/<you content block's controller>" (Example: {:action => index and :controller => "ibo/articles"})

Fixed manually by overwriting a "bulk_update" method and changing redirect_to from ":action :index" to an actual path.
