If you could bisect or give a reproducer > that would be great. I could not reproduce by reindexing with nm 0.32, so I started using nm 0.32 again. Indeed, I got another mis-threading. I reindexed with nm 0.32 (without downgrading) and the thread got separated correctly again. That explains why I was not able to create a reproducer. So it seems: - The mis-threading happens during `notmuch new`, not with `notmuch reindex`. - In this new case (and if I remember correctly also in the others), it's always a new message getting worngly put into an existing thread, and if I'm not mistaken, the existing thread was tagged as trash before in all cases.
