New description:
I was messing around with my state file to simulate various guard
scenarios, and I ended up getting the following non-fatal assert. This
happened when I replaced `confirmed_on=2016` with `confirmed_on=2014` in
my state file, so that I test guard expiry:

This error message appeared on startup and the RSA identity key error
message has nothing to do with `confirmed_on` so that was a bit
surprising.
