I did not. I think this is the reason why it did not work for me. Thank you!

I think the following changes (or similar) would help to avoid such misunderstandings:

--- /usr/share/emacs/27.2/lisp/mail/emacsbug.el.gz
+++ #<buffer emacsbug.el.gz>
@@ -114,7 +114,8 @@
            (start-process "xdg-email" nil "xdg-email"
                           "--subject" subject
                           "--body" body
-                          (concat "mailto:" to)))
+                          (concat "mailto:" to))
+           (display-buffer-below-selected (get-buffer "xdg-email") nil))
        (error "Subject, To or body not found")))))

 (defvar report-emacs-bug--os-description nil

Hello - thanks for your (very well done and pleasant to read!) report.

Another symptom of printing the wrong way, similar to bug#52222.
Printing with `edebug-safe-prin1-to-string' should fix it and be the
right thing, right?

Hmm, that calls `report-emacs-bug-insert-to-mailer'.  You have set up a
mailer on your system and it works all fine?  If you think Emacs is not
behaving here, can you please create a separate report? - that this
works is very important.  Maybe you can already give debugging a try?

Thanks,

Michael.
