OK, I found that a 2008-08-08 checkout works, while a 2008-08-09 one
does not.  This is true of both emacs 22.2 and 23 CVS.  I also tested
on three separate computers: two amd64 boxes and one x86 box.  I think
the problem occurs when an XREF buffer is involved; finding flets
works fine in the 2008-08-08 version.

Next step: I will look at the code, and try to find out what is going
wrong when the following occurs (I suspect `standard-output' does not
contain a valid buffer name):

Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  (save-current-buffer (set-buffer standard-output) (prog1 (progn ... ... ... ... ...) (assert ...) (setq buffer-read-only t)

It is always possible that an external variable is affecting the
functionality.  Remember my last issue, which turned out to be wholly
araneida's fault?  Here are my slime settings in .emacs.  Could any of
these have an effect?

 '(slime-autodoc-mode t)
 '(slime-autodoc-use-multiline-p t)
 '(slime-compilation-finished-hook (quote (slime-maybe-list-compiler-notes slime-maybe-show-xrefs-for-notes)))
 '(slime-complete-symbol-function (quote slime-fuzzy-complete-symbol))
 '(slime-kill-without-query-p t)
 '(slime-multiprocessing t)
 '(slime-repl-history-size 9999)
 '(slime-repl-return-behaviour :send-only-if-after-complete)
 '(slime-startup-animation nil)
 '(slime-truncate-lines nil)
