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. >> (I used it on a trial system but when I reverted to master some things >> seemed to stop working) > > Sorry for breaking it :) 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 Mark
