Gnus pop3 error

[Leon]

Hi all,

I have exactly the same configure file on two machines: one works
perfectly and the other has a few issues. They both run emacs CVS
20060608 and the default gnus 5.11. One of the errors is:

,----
| Debugger entered--Lisp error: (wrong-type-argument processp nil)
|   process-buffer(nil)
|   pop3-read-response(nil t)
|   pop3-open-server("pop.gmail.com" 995)
|   pop3-movemail("~/.emacs-mail-crash-box")
|   ......
|   nnmail-get-new-mail(nnml nnml-save-nov "~/mor/gnus/Mail" "mail.misc")
|   nnml-request-scan("mail.misc" "")
|   gnus-request-scan("nnml:mail.misc" (nnml ""))
|   gnus-activate-group("nnml:mail.misc" scan)
|   gnus-group-get-new-news-this-group(nil)
|   gnus-topic-get-new-news-this-topic(nil)
|   call-interactively(gnus-topic-get-new-news-this-topic)
`----

Any ideas?

Thank you.
