Yeah, I probably managed to make it use ~/.notmuch-config somehow.

The were a bunch of weird characters that looked like unicode
test-cases, the pytest tests don't try to test notmuch only the bindings
so doesn't really make up weird strings IIRC.  I recovered with
something like "notmuch dump | cleanup_tags.py | notmuch restore", oh
well.

I still have a bunch of non-existing messages with weird unicode message
IDs in them, but no associated filename just an empty string.  AFAIK
notmuch_database_remove_message() needs a filename though, I've tried
removing the empty file which does not fail but doesn't clear those
database entries.  The messages are not ghosts either.  Any idea how I
might be able to clear those bad messages from the database?

Cheers,
