Are you saying that the above code makes it break if you use the
settings below?

That would be really weird, for the settings below do not use the
above code at all!  How can code that isn't used break anything?

Irrelevant hint: write \\. instead of \. in Lisp strings in regexes
when you mean a literal dot.  For regexes in Lisp strings,
backslashes need to be doubled.

But since you do not use %k in gnus-summary-line-format, you can
easily turn my code off.

PS: I had "below settings" instead of "settings below" in an earlier
    draft of this message, but then changed it because it looked
    strange.  Yet, "above code" and "below settings" appear to be
    quite analogous.  Hm.  Maybe I could have used "code above"
    together with "settings below" for consistency.

    Which is (are) correct?
