ah, I see! So, does that mean the list itself is represented as an
always-present dummy-node that resides in the list?
However, it looks like the crash occurred as a result of
es->destroy_signal.listener_list.prev being NULL. Somehow, this list ceased to
be circular (at least while traversing backwards)
