Hello,

To reduce startup time, I usually start Gnus with M-x gnus-no-server,
and type M-g to check certain groups.  However, it seems to be broken
for a while:

Debugger entered--Lisp error: (error "server/993 Name or service not known")
  make-network-process(:name "*nnimap*" :buffer #<buffer  *nnimap server nil  *nntpd**> :host "server" :service "993" :nowait nil)
  open-network-stream("*nnimap*" #<buffer  *nnimap server nil  *nntpd**> "server" "993")
  open-gnutls-stream("*nnimap*" #<buffer  *nnimap server nil  *nntpd**> "server" "993")
  ...
  nnimap-open-connection-1(#<buffer  *nntpd*>)
  nnimap-open-connection(#<buffer  *nntpd*>)
  nnimap-open-server("server" nil nil)
  nnimap-change-group(nil "server")
  nnimap-request-group-scan("INBOX" "server" ...)
  gnus-request-group-scan("nnimap+server:INBOX" ...)
  gnus-group-get-new-news-this-group(nil)
  gnus-topic-get-new-news-this-topic(nil)
  funcall-interactively(gnus-topic-get-new-news-this-topic nil)
  call-interactively(gnus-topic-get-new-news-this-topic nil nil)
  command-execute(gnus-topic-get-new-news-this-topic)

Comparing the backtrace with the one taken with M-x debug-on-entry
open-network-stream on Emacs 24.4, the DEFS argument of
`nnimap-open-server' is not given on the first connection.

Any ideas on this?

Regards,
