OK. Your reproduction scenario is the following?
If not, could you show me the complete scenario?

1. start the primary
2. pg_start_backup()
3. copy $PGDATA from the primary to the standby
4. pg_stop_backup();
5. create the recovery.conf and start the standby
6. shutdown (smart mode) the standby
7. start the standby again
   --> cannot accept connnections until new WAL has been created
