New description:

 Noticed this error after updating to WP 5.2 on PHP 7.3. This error may be
 related to errors thrown in caching plugins, or other drop-ins which
 execute and error early.

 My error was thrown after a fatal error in WP Redis:
 > Uncaught RedisException: Connection timed out

 I Googled to see if anything had been written on this issue and found a
 completely separate live website presenting the same error (I am not
 associated with this website): http://masacoat-asahi.com/

 It appears this code was introduced in #47093 (changeset 45277) to fix an
 issue with recovery mode emails locale.

 Suggest a conditional for if locale is not defined yet.
