What do you have in 'notmuch config get new.ignore'? Have you changed
this setting recently?

I could reproduce something similar by adding an ignore on a folder that
had files indexed by notmuch:

$ cd /path/to/maildir
$ mkdir foo
$ mkdir bar
$ # deliver a message to foo/baz
$ notmuch new
Processed 1 file in almost no time.
Added 1 new message to the database.
$ notmuch config set new.ignore foo
$ mv foo/baz bar
$ notmuch new --debug
(D) add_files_recursive, pass 1: explicitly ignoring /path/to/maildir/foo
Processed 1 file in almost no time.
No new mail.
$ notmuch search --output=files folder:bar
/path/to/maildir/foo/baz
/path/to/maildir/bar/baz

Note that the last search finds messages that have at least one
associated file in a folder matching bar, and then outputs *all* the
associated files for the messages. Here, the ignore has caused notmuch
to not notice the file in foo has been deleted.
