This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing
list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Short version : Emacs can no longer use spell checking

I have been using a CVS derived carbon build of emacs on OS X for some
time, and this new version has a bug running /usr/local/bin/aspell:

In GNU Emacs 22.0.50.1 (powerpc-apple-darwin8.4.0)
 of 2006-01-19 on Reason.local
X server distributor `Apple Computers', version 10.4.4
configured using `configure '--without-x' '--with-kerboros'
'--with-kerberos5' '--prefix=/usr/local''

I have been using this version of aspell for some time:

/usr/local/bin/aspell -v
@(#) International Ispell Version 3.1.20 (but really Aspell 0.60.2)

The error occurs when Emacs tries to start "ispell".  The *Messages*
buffer shows this when I call "ispell-buffer"

Loading ispell...done
Starting new Ispell process...
Spell checking *scratch* using aspell with default dictionary...
Spell-checking using aspell with default dictionary done
ispell-get-line: Wrong type argument: stringp, nil

The value for ispell-program-name is "/usr/local/bin/aspell", derived
from the default list expression:
(or
 (locate-file "aspell" exec-path exec-suffixes 'file-executable-p)
 "ispell")

This error prevents me from spell checking anything within Emacs.  This
is a show stopper for documents.

This error is independent of my ~/.emacs file (I moved it out of the way
and it had no effect). If my ~/.aspell.conf would be interesting, then I
could send it.  But I tried moving it out of the way and nothing improved.

I checked that this error is still present in CVS from now:
$ date
Sun Jan 22 23:00:31 GMT 2006

Looking as emacs/lisp/ChangeLog indicates that ispell and flyspell code
has been changed recently.  So I expect that this is mainly bad timing
on my part.

This error did not occur for my previous checkout(s) from CVS.  In
particular the next-most-recent which I have now reverted to is this
vintage:

In GNU Emacs 22.0.50.1 (powerpc-apple-darwin8.2.0)
 of 2005-07-30 on Reason.local
X server distributor `Apple Computers', version 10.4.4
configured using `configure '--without-x' '--prefix=/usr/local''

This older works flawlessly.  It finds /usr/local/bin/aspell and calls
it without a hitch.  I cannot see any difference in how Emacs is
configured between the old and new versions.

Cheers,
  Chris Kuklewicz

This variable is nil in the older working version of cvs-emacs

This variable does not exist in the newer broken version of cvs-emacs

Yes, the problem is identical if I use those options.

I have read the email messages you pointed to and found a workaround:  If I run
the command ispell-change-dictionary and select one of the options (e.g.
american) then spell checking starts working.  This command creates
ispell-dictionary and sets it to nil and it creates the previous missing
ispell-local-dictionary and sets it to american.

This can be made permanent: Adding (setq ispell-dictionary "american") to my
~/.emacs causes ispell-dictionary to be set properly and it leaves
ispell-local-dictionary uncreated.  After performing ispell-buffer, I notice
ispell-local-dictionary has been created and set to nil.

Conclusion: It seems there is a problem in the latest cvs version where
ispell-dictionary is not being created by default (and set to nil) and this
prevents ispell from working for me.

This seems the same problem described by Stefan Monnier in the "Problems
with ispell/flyspell" thread when no english aspell dict is available,

http://lists.gnu.org/archive/html/emacs-devel/2005-12/msg01343.html

where he proposed making sure a sane default is available by using first
entry of ispell-dictionary-alist-1 when nothing else works.

Attached patch seems to take care of that,
