I'm not sure what went wrong here, or how to fix it. The logcat shows the next test - foreignObject-start-hidden-02.svg - running, but then ends abruptly. Did the emulator become unresponsive? Even so, NamedTemporaryFile should have created the file...how could it have been deleted prior to the NamedTemporaryFile destruction?
