I did end up tracking down the offending metric and charts, All of them are
the same metric, with no extra tags, but it is one that I have added to the
system, cpm (radiation counts per minute). The day graph works, but the
weekly, monthly and yearly all fail, with the traceback listed above.
There are excerpts from the database listed above.
[[month_images]]
x_label_format = %d
bottom_label_format = %x %X
time_length = 2592000 # == 30 days
aggregate_type = avg
aggregate_interval = 10800 # == 3 hours
show_daynight = false
.........
[[[weekRadiation]]]
[[[[cpm]]]]
