advance search->select all->schedule/send a mass mailing: Total recipients: 0 (incorrect)

Upgraded from 4.1.2 to 4.3.4. Drupal 7.
If you select all contacts using advance search, and select action 'schedule/send a mass mailing', fill the mailing fields and go next screen, it shows Total recipients: 0. This used to work fine in 4.1.2 and several previous versions. Tried on current Demo site (drupal 7) able to reproduce. This is a civimail key functionality.
