error creating an imap group

[Dan Christensen <jdc@jhu.edu>]

Every time I create an nnimap group with `G m', I get the error:

Imap-mailbox-data is nil. Property uidvalidity value 929131668 mailbox debian2

This is with nnimap 0.116 and pgnus 0.87 with the gnus-agent.el,
nnagent.el and gnus-cache.el patches applied, but it also happened
with the only other versions I tried, 0.114 and 0.84 resp.

Emacs doesn't return to "command mode" until I hit C-g, but it does
produce a backtrace if I have debug-on-error set:

Signaling: (error "Imap-mailbox-data is nil. Property uidvalidity value 929131668 mailbox debian2")
  signal(error ("Imap-mailbox-data is nil. Property uidvalidity value 929131668 mailbox debian2"))
  error("Imap-mailbox-data is nil. Property %s value %s mailbox %s" uidvalidity "929131668" "debian2")
  imap-mailbox-put(uidvalidity "929131668" "debian2")
  imap-parse-status()
  imap-parse-response()
  imap-arrival-filter(#<process imap> "* STATUS debian2 (UIDVALIDITY 929131668)

  accept-process-output(#<process imap> 1)
  imap-wait-for-tag(4 nil)
  imap-send-command-wait(("STATUS " "\"debian2\"" " " "(uidvalidity)"))
  imap-mailbox-status("debian2" uidvalidity " *nnimap* chow.mat.jhu.edu")
  ad-Orig-nnimap-request-create-group("debian2" "chow.mat.jhu.edu" nil)
  (setq ad-return-value (ad-Orig-nnimap-request-create-group group server args))
  (let ((trace-level ...) (trace-buffer ...)) (save-excursion (set-buffer trace-buffer) (goto-char ...) (if ... ...) (insert ...)) (setq ad-return-value (ad-Orig-nnimap-request-create-group group server args)) (save-excursion (set-buffer trace-buffer) (goto-char ...) (insert ...)))
  (let (ad-return-value) (let (... ...) (save-excursion ... ... ... ...) (setq ad-return-value ...) (save-excursion ... ... ...)) ad-return-value)
  nnimap-request-create-group("debian2" "chow.mat.jhu.edu" nil)
  gnus-request-create-group("nnimap+chow.mat.jhu.edu:debian2" nil nil)
  gnus-group-make-group("debian2" (nnimap "chow.mat.jhu.edu"))
* call-interactively(gnus-group-make-group)

The group works fine after I hit C-g (or `q' from the backtrace).  Any ideas?
