Hello, I’m on notmuch 0.33.1 and I’m still having issues displaying messages in long threads when the messages are encrypted. I have such a thread with more than 600 messages, and when I do the following: - search for the messages - run notmuch-tree-from-search-current-query I get an error (I only show the top of the backtrace, it’s really huge): Debugger entered--Lisp error: (error "Lisp nesting exceeds ‘max-lisp-eval-depth’") apply(concat "...") replace-regexp-in-string("^\\([Rr]e: *\\)+" "" "...") notmuch-show-strip-re("...") notmuch-tree-format-field("subject" "%s" (:id "Mr.isFiQDKYZxD.GlhHReZivPr@polytechnique.org" :match t :excluded nil :filename ("/home/schmitta/.Maildir/o2switch/.INBOX.DeltaChat/...") :timestamp 1629630478 :date_relative "August 22" :tags ("encrypted") :crypto nil :headers (:Subject "..." :From "" :To "***" :Date "Sun, 22 Aug 2021 11:07:58 +0000") :first nil :tree-status ("┬►" "╰" " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " ...) :orig-tags ("encrypted"))) notmuch-tree-format-field-list((("tree" .
