Whenever I call 'superclasses' on a symbol I get an error saying
CLASS-FINALIZED-P cannot be called on a NIL. Is this intended behavior
of 'superclasses' or am I doing something wrong?

WTF is 'superclasses? (Don't tell me, give me the 'apropos output.)

<sigh>

Could you be more specific? What function did you call exactly?

Also: What Common Lisp implementation are you using, and in which version?

It may be better to ask such questions in the closer mailing list.

Whoops, a thousand apologies. The function 'superclasses' is part of
moptilities, not closer-mop. I should have known better than to post
at 3AM.

Nonsense. 25min later you had your answer, and an answer that will serve 
in similar situations for decades to come.

Oh, wait, maybe you ignored me....
