rspec users - May 2010 - Strange issue with the 'its' construct

The ''its'' construct seems to not be working for me. I have
narrowed it
down to a basic example that I think should be working. Note that when I
use a normal ''it'' block with a subject in it, that works fine.

Any insights would be welcome: http://gist.github.com/407789

Cheers, Tom.

Please file a bug at https://rspec.lighthouseapp.com/projects/5645-rspec if
there''s not one already.

I was unable to find one, so I created this:
https://rspec.lighthouseapp.com/projects/5645-rspec/tickets/998-explicit-subject-block-in-a-controller-spec-returns-the-controller-instead-of-the-subject-defined-in-the-example-group

Another finding is that this only occurs when running the file from 
spec/controllers, it''s fine when run from spec/models. Details are on 
the ticket.

Thanks, Tom
