The problem is *not* fixed.  

I was the one who reported this problem two years ago.  I did the
same notmuch search again.  Since I did no know if it's important
with which version the emails were indexed I did a full index
with notmuch 0.17+40~gecbb29e.

I still have the mbox produced with notmuch show two years ago.
Viewed with mutt (1) I see 206 messages in 7 threads (number of
lines after collapse-all) (notmuch emacs show showed three
threads then).  One of the threads is the one I searched for.

Today I produced another mbox with the very same command but with
a now larger email corpus freshly indexed with a fresh notmuch.
The mbox contains (according to mutt) 507 messages in 34 threads.
One of them is the thread I searched for.

I grepped for the 7 subjects within the 34 subjects and only 5
showed up.

Only 17 of the 507 messages arrived since the problem report two
years ago.

If somebody want's to dig into this: I can provide the two
mboxes. 

Disclaimer: Many of the emails which arrived before the problem
report are not the exact same than then, because since the I
mangled them with a script.  This should have not changed the
threading but I cannot be 100% sure.  But if it's important for
further investigation I'm probably able to reproduce the status
quo of the email corpus then from my backups.

Thanks for your persistence. 

Ciao, Gregor
