Error during redisplay: (eval (tabbar-line)) signaled (wrong-type-argument consp nil)

When I got the newest version of tabbar-ruler, and tried to open Emacs in terminal with argument -nw, I got an error of this:

Error during redisplay: (eval (tabbar-line)) signaled (wrong-type-argument consp nil)

I'm at Mac terminal with GNU Emacs, and the error raised from here:

1. tabbar-line-format calls tabbar-line-tab
2. In tabbar-line-tab, variable close-buttong-image gets a nil value, in tabbar-ruler.el at line 1384
3. tabbar-line-tab calls tabbar-normalize-image at line 1393, with a nil image
4. Finally an error raised in tabbar-normalize-image at line 1113, by expression: (setcdr image plist)

The function tabbar-find-image in tabbar will always return nil dues to (display-images-p) always returns false. So I think maybe tabbar-normalize-image should check the first argument to avoid raising error. I temporarily override this in my .emacs file

(defadvice tabbar-normalize-image (around check-first-arg activate)
   (when (ad-get-arg 0)
    ad-do-it))

Thank you. I'm sorry it took so long.
