Ethereal just says that theres nothing to display as no data has been captured.
Ethereal's opening the pipe in non-blocking mode, but it's not turning non-blocking mode off on the pipe once that completes, so if it tries reading from the pipe before something opens the pipe for writing, it'll get an EOF and assume that there's nothing more to read.
