I do not think it's wrong. There's no vector involed here.

In your backtrace I see
   gnus-configure-frame((vertical 1.0 (group 1 point)))

I cannot find such a line in Gnus code source.

In gnus-win there something that looks like it which is:
  '((group
     (vertical 1.0
	       (group 1.0 point)))

But it's 1 dot zero.

So I don't get where it come from. Maybe you have an very definition of
the gnus-buffer-configuration variable? If that's possible.
