Capybara get error `block (2 levels) in <top (required)>' - selenium

Question

Spent whole day with the problem.
Very simple test. I want to visit main page and check if it has text "Match".
require 'spec_helper'
describe "Sign in" do
it "should sign in with correct data", :js => true do
visit root_path
page.should have_content("Match")
end
end
Running rake spec:requests I've got:
1) Sign in should sign in with correct data
Failure/Error: visit root_path
Timeout::Error:
Timeout::Error
# ./spec/requests/signin_spec.rb:5:in `block (2 levels) in <top (required)>'
Can't fix it. It doesn't work with or without spork and guard, and making me crazy :(
My environment:
Gemfile:
group :test, :development do
gem 'rspec-rails', '2.7.0' , :branch => 'rails3'
gem 'capybara'
gem 'guard'
gem 'guard-rspec'
gem 'guard-spork'
gem 'growl'
gem 'launchy'
gem 'growl_notify', :require => false if RUBY_PLATFORM =~/darwin/i
gem 'rb-fsevent', :require => false if RUBY_PLATFORM =~/darwin/i
end
spec_helper.rb:
require 'rubygems'
require 'spork'
Spork.prefork do
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
# Add this to load Capybara integration:

RSpec.configure do |config|
# Loading more in this block will cause your tests to run faster. However,
