message-default-mail-headers not working in notmuch 0.22

[Sebastian Fischmeister]

Hi,

After upgrading to notmuch 0.22, my emacs config seems broken:

(setq message-default-mail-headers "Reply-to: me at example.com\nBcc: me at example.com")

When creating a new mail, it has no header other than "To:" and
"Subject:".

Since I cannot find any item in the NEWS related to this release, is
this expected behaviour?
