The breakage I observed was when trying to reply to a message after
reverting to master: on the command line I got

Error opening /database_path/maildir:///full_path_of_file: No such file or directory

When doing notmuch search output=files I see both possibilities.

Surprisingly notmuch new does not seem to remove these entries.

It was no problem for me: it was just a test corpus of 10,000 message
that I use for testing.

In case anyone else has problems the following solved it for me:

1) dump the tags
2) delete the .notmuch subdirectory of the mail store 
3) run notmuch new
4) restore the tags

Best wishes
