Same question, but solution did not work:, I've tried several versions of rspec: Why is Rspec saying "Failure/Error: Unable to find matching line from backtrace"?
dpalacio:sample_app dpalacio$ rspec -v
2.0.0.beta.18
dpalacio:sample_app dpalacio$ rspec spec/
controllers/    factories.rb    models/         requests/       spec_helper.rb  
dpalacio:sample_app dpalacio$ rspec spec/requests/

And the same with the 2.0.1 version:
dpalacio:sample_app dpalacio$ rspec -v
2.0.1
dpalacio:sample_app dpalacio$ rspec spec/
controllers/    factories.rb    models/         requests/       spec_helper.rb

Ok found the issue, the issue is not RSPEC but WEBRAT. Add to your Gemfile:
gem 'webrat', '0.7.1'
The version of RSPEC should be: gem 'rspec', '2.0.1'
It's hard to see this as a (purely) webrat issue ...
group :test, :development do
  gem 'rspec-rails', '2.0.0.beta.18'
  gem 'capybara'
  gem 'database_cleaner'
  gem 'cucumber-rails'
  gem 'cucumber'
  gem 'spork'
  gem 'launchy'
end
... since I'm using capybara instead of webrat.
Any ideas are welcome.
This doesn't seem to be an issue as of rspec 2.2.0
