error: Selecting deleted buffer

Any hints as to where to start looking?

Maybe the error goes away with 5.8.7?  That'd be the first thing I'd try.

It was working fine until yesterday.  I had a corrupt telnet session (lots
of garbage characters sent by mistake), then this started happening.  

I suppose I'll just bite the bullet and upgrade.  Everything was working
fine for me with 5.8.3, so I was hoping to stay with it until a "final"
release came out.

Thanks for the feedback.

Did you restart Emacs after that?  If so, then the only thing that
could have happened is that some files are corrupted.  But the error
doesn't sound like it.

Yes, I restarted emacs.  I looked through my .newsrc.eld file, and could not
identify any problems.  Neither my .gnus.el nor my .emacs file were changed.

I've run gnus-group-check-bogus-groups, and browsed the nntp server from the
server mode.

sigh.  I'll wait a day in case someone posts "The problem is obviously xxx.
Do yyy and it will be fixed", then upgrade and see what happens.

Thanks again.

I upgraded to 5.8.7, and the problem persists.  The error occurs right after
a message indicating the active file has been read from my nntp server.  If
I hit "g" again, it works fine.

I removed the killed and zombie lists from .newsrc.eld, and went over my
.gnus.el, and can not find any problems.

Any suggestions as to where to start looking?

Thanks

I saw a similar bug report before.  But I can not figure out which
buffer causes the problem.  One buffer is " *nntpd*" and another is 
" *server SERVER nntp *nntpd**" (notice the leading space. replace
SERVER with the real server name).  If the problem happens again,
could you check all buffers starting with " *"?  I guess some buffer
is missing.

(print(buffer-list) (current-buffer))
(#<buffer *scratch*> #<buffer  *Minibuf-1*> #<buffer *Backtrace*> #<buffer *Group*> #<buffer  *Minibuf-0*> #<buffer *Messages*> #<buffer  *mh-temp*> #<buffer  *nntpd*> #<buffer .newsrc-dribble> #<buffer  *gnus work*> #<buffer  *nnmail message-id cache*>)


So it appears that the ...SERVER... buffer is missing.

I guess Gnus lost the connection to the SERVER in the middle of
retrieving groups.  So, you have to make a new connection by typing
`g' or so.

I'll sniff packets to try and determine which end is closing the
connection.  Hopefully, it is not gnus.
