Here's a more detailed report. Sorry for not having used report-emacs-bug.

My Emacs version is GNU Emacs 23.0.90.1 (i686-pc-linux-gnu, GTK+ Version
2.8.20) of 2009-02-08

To trigger the bug, type the following in the *scratch* buffer:

(defun foo ())
M-x eval-buffer RET
M-x apropos-library RET

Backtrace:

Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  file-name-nondirectory(nil)
  (setq l (file-name-nondirectory l))
  (lambda (l) (setq l (file-name-nondirectory l)) (while (not ...)) l)(nil)
  mapcar((lambda (l) (setq l (file-name-nondirectory l)) (while (not ...)) l) 
(...))
  (delq nil (mapcar (lambda ... ... ... l) (mapcar ... load-history)))
  (nconc (delq nil (mapcar ... ...)) (mapcar (quote car) load-history))
  (let ((libs ...)) (list (completing-read "Describe library: " libs nil t)))
  call-interactively(apropos-library t nil)
  execute-extended-command(nil)
  call-interactively(execute-extended-command nil nil)

I hope this helps.
