> 2) From the *Group* buffer I hit `C-g` to cancel its attempt, and `^` to

> 3) In that buffer I go to the imap connection and type `C O`, which runs

Breakpoint or segfault?

> `g` calls the following function:
> 
>     (defun gnus-server-exit ()
>       "Return to the group buffer."
>       (interactive nil gnus-server-mode)
>       (gnus-run-hooks 'gnus-server-exit-hook)
>       (gnus-kill-buffer (current-buffer))

What is current-buffer at this point?
