Can you please evaluate the following on your system:

  (call-process "notmuch" nil t nil "show" "--format=raw" "id:87a7zsm5ol.fsf@gmail.com")

If I do this on my system, then the text that is inserted into the
buffer has ^M (CR) at the line endings. Is this expected?

In contrast, if I evaluate the following:

  (require 'subr-x)
  (find-file (string-trim
              (shell-command-to-string "notmuch search --output=files id:87a7zsm5ol.fsf@gmail.com")))

then a buffer with the message is opened but with clean line endings (no ^M).

Yes, bounce is also not working in this mode. I only evaluated 

  (setq message-send-mail-function (lambda () t))
  (notmuch-hello)

from the startup page (I have not loaded my ~/.emacs). But still the
bounce fails with:

  Search failed: "

  "

as message in the minibuffer.
