A bug I can't seem to track down

[John Wiegley]

Sometimes, when I follow these steps:

1. Don't start Gnus.

2. Run this code, letting it start Gnus:

(defun gnus-query (query)
(interactive "sMail Query: ")
(let ((nnir-imap-default-search-key "imap"))
(funcall
(symbol-function 'gnus-group-make-nnir-group)
nil
`((query . ,query)
(criteria . "")
(server . "nnimap:Local") ))))

3. Search for something you know is there (you'll have to change 'server' to
your IMAP server's name).

4. Read the first article it finds.

5. Hit 'q' to leave the summary buffer.

I get this trace:

--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (error "No such setting in `gnus-buffer-configuration': nil")
signal(error ("No such setting in `gnus-buffer-configuration': nil"))
error("No such setting in `gnus-buffer-configuration': %s" nil)
gnus-configure-windows(nil force)
gnus-handle-ephemeral-exit((#<buffer *Group*>))
gnus-summary-exit()
call-interactively(gnus-summary-exit nil nil)
--8<---------------cut here---------------end--------------->8---

If I go to the definition of gnus-configure-windows, and eval the buffer, the
same steps will not reproduce the problem.

And generally, if I start Gnus first before doing the search, I don't see this
problem.
