Subject: 24.0.50; buffer loads in minibuffer and does not go away
Date: Sun, 11 Sep 2011 09:26:14 +0530

Hello

Emacs commands are prefixed with ;
Shell commands are prefixed with $

$ emacs -Q

; (setq-default enable-recursive-minibuffers 't)
; M-: (setenv
; C-h f
; C-x o
; C-x o
Now point is in the help buffer, TAB and open env.el

The file opens up in the minibuffer.  After that, I couldn't find an
easy way to close it (see below).

Buffers should never open up in the minibuffer.

The same bug occurs even when enable-recursive-minibuffers is nil.
However, in that case, the problem is goes away the next time you try
to access the minibuffer (M-x, M-: etc).  If I set
enable-recursive-minibuffers back to nil, then the problem goes away.

I've traced the bug to select-window which is defined in src/window.c
I'm going through it but I still haven't figured out how to build
emacs in Windows.

Below is the report generated by Emacs.

I cannot reproduce this with the current trunk. Yours seems to be 3
months old?

I tried this on trunk in a GNU/Linux and it worked fine.  This bug can
be closed.

Gnus should be more complicated.
