When I'm at home, none of the IMAP servers at work are available, so I 
would like to deny them.

However if I go to the server buffer, and press D on these servers,
and then go back to *Group* and press 
	g
I end up with the following stack trace:

Signaling: (wrong-type-argument stringp nil)
  set-buffer(nil)
  (save-current-buffer (set-buffer nnimap-server-buffer) (when (and ... ...) (case nnimap-expunge-on-close ... ... ...) (not imap-current-mailbox)))
)
  (with-current-buffer nnimap-server-buffer (when (and ... ...) (case nnimap-expunge-on-close ... ... ...) (not imap-current-mailbox)))
)
  nnimap-close-group("INBOX" "somemachine.somecompany.no")
  gnus-get-unread-articles(2)
  gnus-group-get-new-news(2)
  call-interactively(gnus-group-get-new-news)

Anyone's got an idea what is wrong?
