single test failing after changing to capybara-webkit
===

I have written some RSpec test for my rails 3.2 application and because I was annyoed by the Browser popping up ich tried to change from firefox to `capybara-webkit`.
After this all tests still run, except one. The line that is failing is:

    expect { click_button "Create" }.to change(Answer, :count).by(count)

If I remove the expect and add a method to take a screenshot before and after, I can see that the test is run correctly. But if I step trough with the Debugger the log shows me that the records get created after the second screenshot line. I can wait forever the click_button and corresponding Controller action is run after the line next line is executed.

The "create" button is a standard html button, no JS is involved in the create action. Does sb have a explaination for this strange behaviour?
