This looks similar to https://gitlab.gnome.org/GNOME/gtk/-/issues/1498 .

Since this bug is a crash in the signal handler, it might be possible
to sidestep the issue by updating the widget after the signal handler
is done, using a timer - something along the lines of

def on_activate_link(self, label, uri):
   if uri == 'rename':
     GLib.timeout_add(20, self._update_markup)
     return True

def _update_markup(self):
   self._feed_label.set_markup(....)
