Dear notmuch developers,

please find attached an redacted copy of an actual email in my
Maildir which notmuch does not find, even not with

path:inbox/**

as search term (as opposed to other mail in inbox/cur/ which
shows up fine).

I can see and read this very mail with mutt and mairix find's it.

Actually this very email is filed in three maildirs (inbox, sent,
outbox) which are all indexed by notmuch and mairix finds all of
them.

I did a test with a modified .notmuch-config, provided a database
path /tmp/Mail, did mkdir -p /tmp/Mail/inbox{cur,new,tmp}, copied
this file into /tmp/Mail/inbox/cur, did a
NOTMUCH_CONFIG=/tmp/.notmuch-config notmuch new, and then notmuch
find this very email just fine.

I'm astonished.  Otherwise notmuch works great.  Any ideas why
this mail does not show up in my inbox or how to debug this?

Thanks for your attention, Gregor
