Subject: Weird article scrolling in Gnus with customized face

Ok, I start up Gnus. Now, if I view an article by hitting RET
(`gnus-summary-scroll-up') on it in *Summary*, I get the following
behavior:

  - as long as there are visible headers (Subject, From, etc.) on top of
    the buffer, pressing RET scrolls exactly one line as it should be.

  - when the last visible header scrolled out of the visible buffer part
    pressing RET results in scrolling one entire page like SPACE
    (`gnus-summary-next-page') does.

  - the same applies to M-RET

I tried it on a test account, and all worked fine. But I was able to
locate the source of the problem: One customized face is causing the
trouble!

(custom-set-faces
 '(mode-line ((((class color) (min-colors 88)) (:background "darkred" 
:foreground "grey" :box (:line-width 1 :style released-button) :height 0.8 
:family "helvetica")))))

If I commend out this line, scrolling works as it should. With this line
I can reproduce the bug in both No Gnus and 5-11.
