Ignore 'bad file descriptor' errors. Seems to be the right thing to do. Judging from some research this may be caused from broken libraries. The gist is though that dials *should* attempt to read from STDIN unless it is run off a terminal. But if reading from STDIN fails for *technical* reasons this should be fine. Parsing errors etc. are a different matter. Closes #326
