Occasionally when I restart weewx I see this error:

Apr 27 22:00:15 HOSTNAME weewx[16906]: rtgdthread: Traceback (most recent call last): Apr 27 22:00:15 HOSTNAME weewx[16906]: rtgdthread: File "/usr/share/weewx/user/rtgd.py", line 926, in process_packet Apr 27 22:00:15 HOSTNAME weewx[16906]: rtgdthread: data = self.calculate(cached_packet) Apr 27 22:00:15 HOSTNAME weewx[16906]: rtgdthread: File "/usr/share/weewx/user/rtgd.py", line 1519, in calculate Apr 27 22:00:15 HOSTNAME weewx[16906]: rtgdthread: fromBearing = max((self.windDirAvg-d) if ((d-self.windDirAvg) < 0 < s) else None for x, y, s, d, t in self.buffer.wind_dir_list) Apr 27 22:00:15 HOSTNAME weewx[16906]: rtgdthread: ValueError: max() arg is an empty sequence
