`date-to-time' has:

         (condition-case-unless-debug err
             (encode-time (parse-time-string
                           (timezone-make-date-arpa-standard date)))

As you have `debug-on-error' set, this looks like the expected
behaviour.

The `condition-case-unless-debug' was added by Stefan in commit
cb411c609d43 on April 19th. Perhaps this is left over debugging code ?
