gnus error (Selecting deleted buffer)

[Roger Mason]

Hello,

I'm trying to get e-mail from my university server using gnus/imap.  I
have this entry in my .gnus file:

(setq mail-sources '(
;(file :path "/var/spool/mail/ted") 
                     (imap :server "xx.yy.zz"
                           :user "ted"
                           )
)) ;where to get mail


Mail source (imap :server mail.mun.ca :user ted) error (Selecting
deleted buffer).  Continue? (yes or no)

No matter if I say yes or no to the question, mail is not fetched from
the server.

I'm running gnus 5.10.8 in GNU Emacs 22.1.1 (i686-pc-linux-gnu, GTK+
Version 2.10.14) of 2007-10-29 on minnie

I guess I have something mis-configured.  Any help will be much
appreciated.

Roger
