Yes, the extra ones all are ghosts, and I slowly remember that they scared me in the past already ... These ghosts appear to be pretty common. It happens all the time that I am joined to an existing discussion thread where I do not have all references. I'd go as far as to say that counting ghosts as thread members makes this useless for me. On the other hand, notmuch's own count gets this right. And getting different counts is even more confusing. > 2) Do they have more than one G term? That suggests a bug somewhere.

But their sheer number looks suspicious: those 5 "real" e-mails have maybe 20 reference headers in total, and some of them refer to some of those 5. Grepping the account store for those references gives me around that number. Where do the 110 ghosts (90 extra) come from which this thread points to? Still scared by them ... we need ghost busters!
