The code in add_file seems to assume that NOTMUCH_STATUS_FILE_ERROR is
never returned from add_message. This turns out to be false (although it
seems to only happen in certain fairly rare race conditions).
fprintf (stderr, "Note: Ignoring non-mail file: %s\n", filename);
break;
/* Fatal issues. Don't process anymore. */
+ case NOTMUCH_STATUS_FILE_ERROR:
+ fprintf (stderr, "Unexpected error with file %s\n", filename);
+ (void) print_status_database ("add_file", notmuch, status);
+ goto DONE;
case NOTMUCH_STATUS_READ_ONLY_DATABASE:
case NOTMUCH_STATUS_XAPIAN_EXCEPTION:
case NOTMUCH_STATUS_OUT_OF_MEMORY:
