I'm convinced. Home now so set up a VM running 3.8.2 with no data in the
db. Runs fine. Download user.belchertown_highchartsSearchX.highchartsDay
and add a search_list_extensions option to Standard skin.conf using
user.belchertown_highchartsSearchX.highchartsDay as the only SLE. Runs
without issue (expected). Stop WeeWX, swap in a db with a few months of
simulated data and restart WeeWX and the error occurs:

The first line of the log extract is some telemetry I put in highchartsDay
to log timespan, _start_ts and _end_ts. You can see how timespan is 1
January 2016 to 1 January 2017 which is the first year span of data used by
[[SummaryByYear]], the first report in the skin.
Remove the SLE from skin.conf and all reports are generated without error.
Add the SLE back in and the reports continue to be generated without error
(expected since no historical [[SumaryByxxxxx]] reports are being
generated, only the 'current' ones.
Delete all the NOAA format reports and next report cycle the error is back.
Like I said, I am convinced.
