Bug 71688

I tried run nrwt but it crashed with the -p switch. Crash log the following: worker/0 raised TypeError('must be string or buffer, not bool'): layout_tests/controllers/worker.py:91 (in run) self._worker_connection.run_message_loop() layout_tests/controllers/message_broker.py:191 (in run_message_loop) self._broker.run_message_loop(self._run_topic, self._client, delay_secs) layout_tests/controllers/message_broker.py:127 (in run_message_loop) self._run_loop(topic_name, client, block=True, delay_secs=delay_secs) layout_tests/controllers/message_broker.py:141 (in _run_loop) self._dispatch_message(msg, client) layout_tests/controllers/message_broker.py:150 (in _dispatch_message) message_handler(message.src, *optargs) layout_tests/controllers/worker.py:111 (in handle_test_list) self._run_test(test_input) layout_tests/controllers/worker.py:126 (in _run_test) result = self.run_test_with_timeout(test_input, test_timeout_sec) layout_tests/controllers/worker.py:165 (in run_test_with_timeout) return self._run_test_in_this_thread(test_input) layout_tests/controllers/worker.py:250 (in _run_test_in_this_thread) return self.run_single_test(self._driver, test_input) layout_tests/controllers/worker.py:254 (in run_single_test) test_input, driver, self._name) layout_tests/controllers/single_test_runner.py:46 (in run_single_test) return runner.run() layout_tests/controllers/single_test_runner.py:121 (in run) return self._run_reftest() layout_tests/controllers/single_test_runner.py:290 (in _run_reftest) test_result_writer.write_test_result(self._port, self._test_name, driver_output1, driver_output2, test_result.failures) layout_tests/layout_package/test_result_writer.py:75 (in write_test_result) writer.write_image_diff_files(image_diff) layout_tests/layout_package/test_result_writer.py:208 (in write_image_diff_files) fs.write_binary_file(diff_filename, image_diff) common/system/filesystem.py:205 (in write_binary_file) f.write(contents) In my opinion with the --tolerance switch doesn't run the pixel tests on WK2.
