This issue seems to not be related to a third party package (and the
link to the issue in the dart-mode issue tracker has additionally now
been fixed).  I'm therefore closing this bug report.

With a new ~/.emacs.d and init.el, only containing the following

(setq debug-on-error t)
(setq debug-on-signal t)

I get errors, seen in 27.0.50, about electric-pair-pairs, also tested in
24.5.1, there with ispell-dictionary. I provide more details for the
former. When I start with `emacs -nw`, I see
