[Carlos Garcia Campos]

imported/selenium/py/test/selenium/webdriver/common/alerts_tests.py::testShouldAllowUsersToAcceptAnAlertInAFrame[WebKitGTK] FAILED
imported/selenium/py/test/selenium/webdriver/common/alerts_tests.py::testShouldAllowUsersToAcceptAnAlertInANestedFrame[WebKitGTK] FAILED

Similar backtrace in both cases, it times out waiting for the alert.
