Incorrect generator completion

[schiza]

When I try to use completion with my rails generators:

$ rails g <tab><tab>
controller              mailer                  observer                scaffold_controller
delayed_job             migration               performance_test        session_migration
generator               model                   plugin                  stylesheets
helper                  nibynicmailing:install  resource                
integration_test        nibynicmailing:views    scaffold

And next:

$ rails g niby<tab>
$ rails g nibynicmailing:

Everything works fine. But next:

$ rails g nibynicmailing:<tab>
app/                doc/                lib/                Rakefile            tmp/
config/             Gemfile             log/                README              vendor/
config.ru           Gemfile.lock        public/             script/             
db/                 .gitignore          .rails_generators~  test/ 

Which does an ls in current directory. What it supposed to do (as for me) is:

$ rails g nibynicmailing:<tab>
nibynicmailing:install nibynicmailing:views

I see this too. An easier to reproduce case:

rails generate test_unit:

Hit tab after the colon and it completes files and directories. :(
