Cannot enter Summary Buffer with recent Emacs 23 and No Gnus

Cannot enter Summary Buffer with recent Emacs 23 and No Gnus

[Tassilo Horn]

Hi all,

I use Emacs 23 & No Gnus, both are up-to-date. When I want to enter the Summary
buffer, I get an error signaled and with debug-on-error enabled, I get this
backtrace:

Debugger entered--Lisp error: (error "Invalid size: gnus-carpal")
  signal(error ("Invalid size: gnus-carpal"))
  error("Invalid size: %s" gnus-carpal)
  gnus-configure-frame((vertical 1.0 (summary 1.0 point) (if gnus-carpal (quote
...))))
  gnus-configure-windows(summary force)
  gnus-summary-read-group-1("nntp+Gmane:gmane.emacs.gnus.user" nil t nil nil nil)
  gnus-summary-read-group("nntp+Gmane:gmane.emacs.gnus.user" nil t nil nil nil nil)
  gnus-group-read-group(nil t)
  gnus-group-select-group(nil)
  gnus-topic-select-group(nil)
  call-interactively(gnus-topic-select-group nil nil)

This happens with all groups, no matter what backend is used.  Any clue what
might have broken this?

The last time I did a cvs up on Emacs and Gnus was last Friday, so the
problematic change must have been committed in between that time.  A quick look
at the changelogs didn't find anything obvious, though.

Bye,
Tassilo

Maybe it is due to an Emacs bug: (functionp 'if) => nil
Doesn't this do the trick?

(or (functionp 'if)
    (defadvice functionp (around workaround-bug (object) activate)
      "Workaround bug."
      (or ad-do-it
	  (setq ad-return-value (and (symbolp object) (fboundp object))))))

Indeed.  Befare evaling this, (functionp 'if) return nil.  After
evaluation, it's t again and gnus works as it should.

Thanks for the pointer.

I can confirm this. I'm using an up-to-date CVS Gnus and the latest
emacs-snapshot package from <URL:http://emacs.orebokech.com/> on
Debian. Your workaround fixes this problem. Has anyone already reported
this to the Emacs developers?

Yes, Katsumi did.  See <b4mej9ih34e.fsf@jpl.org> on emacs-devel.

And by the way, Romain has uploaded a new package of emacs-snapshot for
Debian which fixes this isssue as well.
