while running django tests with selenium (no remote, no xvfb), I always get the following exception:

Creating test database for alias 'default'...

Tests are run with LiveServerTestCase using django 1.4 and selenium python-bindings 2.28.0 with Firefox WebDriver. Does someone have an idea, on how to resolve it?

Make sure that the browser requesting the page is waiting for the response.

If i remember correctly there is the selenium_client.implicitly_wait(sec) and selenium_client.set_page_load_timeout(sec) commands for that, make sure you are using it.

If not the server will try to write to a pipe that is broken because the browser close the connection before the response was sent.
