Problems publishing css files

[Richard G Riley <rileyrgdev@googlemail.com>]

Here is my org-publish-project-alist

| (setq org-publish-project-alist
|       '(
| 	("web-css"
| 	 :base-directory "~/webs/rr/"
| 	 :publishing-directory "/ssh:rr@rr.net:/home/rr/webs/rr/"
| 	 :base-extension "css"
| 	 :publishing-function org-publish-attachment
|          :recursive t
| 	 )
| 	("web-images"
| 	 :base-directory "~/webs/rr/"
| 	 :publishing-directory "/ssh:rr@rr.net:/home/rr/webs/rr/"
| 	 :base-extension "gif\\|jpg\\|png"
| 	 :publishing-function org-publish-attachment
|          :recursive t
| 	 )
| 	("web-org"
| 	 :base-directory "~/webs/rr/"
| 	 :publishing-directory "/ssh:rr@rr.net:/home/rr/webs/rr/"
| 	 :base-extension "org"
| 	 :publishing-function org-publish-org-to-html
|          :recursive t
| 	 :section-numbers nil
| 	 :style "<link rel=stylesheet
|                      href=\"./style.css\"
|                      type=\"text/css\">"
| 	 :auto-preamble t
| 	 :auto-postamble t
| 	 :preamble "<div id='Content'><a href='../'>Back</a> - <a href='http://rr.net/default/'>Home</a>"
| 	 :postamble "</div>"
| 	 :author nil
| 	 )
| 	("web"
| 	 :components("web-org" "web-images" "web-css")
| 	 )
| 	)

I can org-publish both web-org and web-images with no problem. However
when I try to publish web-css I get:

,----
| Debugger entered--Lisp error: (error "Wrong type argument: arrayp, nil")
|   signal(error ("Wrong type argument: arrayp, nil"))
|   error("%s" "Wrong type argument: arrayp, nil")
|   byte-code("Â\b!ˆÃÄÅ	!\"‡" [orig-buff act-on-choice icicle-try-switch-buffer error "%s" error-message-string] 4)
|   icicle-execute-extended-command()
|   call-interactively(icicle-execute-extended-command)
`----

I can org-publish-current-file with no problem.

(I have tried it without icicles loaded too). It is only css files (in
this instance) causing this. Any suggestions on how to debug this? What
could it be? I have tried without nxhtml loaded too and have ensured the
only css mode I have in the one that comes with emacs 22.

org : 6.06b
emacs : 22.2.1

Can anyone confirm (using emacs 22) that they can publish css files
without a problem?
