Subject: bug#17256: 24.3.50; minibuffer in main window

From: Richard Stallman <[email-masked]>

I found the minibuffer in the main window.
It was showing a prompt for a buffer name.

C-x b R TAB RET C-a SPC C-d x C-x
C-s C-n C-n C-e C-b ESC b ESC b ESC b ESC w C-x b i
n o u t RET ESC x g r e p RET C-y SPC C-g C-x b RET
C-x C-@ ESC < 

It was at that point.  Then I did
	      
	      C-x b RET

and it switched back to RMAIL.

I don't know how to reproduce it, but it might have to do with the C-x
C-@, which I typed by mistake.  However, shouldn't trying to make a main
window display a minibuffer cause an error?
