This looks like a bug to me. I was able to replicate it in my own mail
store with the script at the end of the message. I haven't completely
analyzed the situation yet, but one thing I noticed is that in all
"bad threads", there are files with duplicate message-ids. Typical
output looks like
╭─ zancas:software/upstream/notmuch/test
╰─ (git)-[master]-% notmuch search thread:000000000001760a
thread:00000000000175e5 November 03 [1/2(3)] 128@gmx.us; Bug#846042: VTK 8 (unread)
thread:000000000001760a 2016-11-27 [1/2(3)] 128@gmx.us; Bug#846042: virtual/meta package for python-vtk (unread)
At least some of this mail data is public, but I'm not sure if the bad
threading is reproducible or not; I want to run a complete census
overnight before I reindex.
Even if the bug is non-deterministic, it probably lives in lib/add-message.cc

count=0
success=0
for id in $(notmuch search --output=threads '*'); do
count=$((count +1))
matches=$((`notmuch search --output=threads "$id" | wc -l`))
if [ "$matches" = 1 ]; then
success=$((success + 1))
else
echo "bad thread: $id"
fi
if [ $((count % 1000)) -eq 0 ]; then
echo $count;
fi
done
echo "count=$count success=$success"
