I do not understand this, and I haven't found a way to repro it from
emacs -Q.  (I can give a much longer recipe, but I doubt you are
interested.)
 
Here is the backtrace.  The first line makes it clear that the list
("c:/drews-lisp-20/CONTRIB/") is not considered `listp'.  But if you
just start with (setq dir-names '("c:/drews-lisp-20/CONTRIB/")) there is
no problem.  Yet `e dir-names' shows that that is the value.  And `e
(listp dir-names)' returns t.  Bizarre.  Dunno whether this report will
help in any way, but this debugger behavior sure seems odd.
 
Debugger entered--Lisp error: (wrong-type-argument listp ("c:/drews-lisp-20=
/CONTRIB/"))
