Subject: can't kill read-only **lose** buffer
Date: Tue, 14 Dec 2010 02:11:59 -0500

I did the following

1) modify a file in the buffer
2) reload the buffer using: c-x c-v

Emacs reports: buffer **lose** is modified; save if first? (y or n)

3) select n

At this point I can't even kill the buffer, if I try to exist emacs i 
can't close it down because of this **lose** buffer, i can't reload the 
buffer or file in the buffer

I am using ido and ecb with my emacs

kind regards,
Rajinder Yadav

Hello Glenn,

it can't be reproduced when I start with "emacs -Q", so it must be ido 
or ecb (addon) that is causing the bug, you can close this, Thanks!

Although ecb is not part of Emacs, this could still be a bug in Emacs.
Seeing the backtrace and the minimal recipe to reproduce it might help
us decide.

I outlined the steps to repro this issue in my 2nd bug report that was 
merged with a similar one I reported a while back.

http://debbugs.gnu.org/cgi/bugreport.cgi?bug=7636

This is really odd, I can't repro the issue anymore. I tried a few 
times. If I am able to repro, how can I get you the backtrace info you 
need. It is a simple as going to the menu help -> send bug report?

    can you turn on "Options => Enter Debugger on Error" in the menus,
    and then reproduce the "Attempt to modify read-only object error"?
    If so, you should then get a backtrace which would help us pin
    point the source of the problem.

I am still unable to repro this issue, should it come up again I will do 
as you stated and reply back with a backtrace!

Thanks again!
