FWIW, I think it was useful for Emacs to show this backtrace (hence
validating the use of condition-case-unless-debug there ;-) because
it makes no sense for
(date-to-time "Session")
to signal the error `(wrong-type-argument char-or-string-p nil)`
IOW, the above backtrace indicates a bug somewhere within date-to-time,
which should signal *another* error.
