error Selecting deleted or non-existent buffer

error Selecting deleted or non-existent buffer

[Steinar Bang]

Platform: Gnus v5.8.8 (CVS checkout from yesterday), XEmacs 20.4, linux

Setup:
 - primary server an nntp server which connects through
   nntp-rlogin-program ssh to a different machine which is allowed to
   talk to this servers
 - nnimap folders
 - a secondary nnimap cyrus server server that always is reachable
 - a secondary UoW nnimap server that is reached through ssh via
   imap-shell-program 
 - a secondary Exchange nnimap server that is not reachable apart from 
   at work.  Currently denied manually in the server buffer 
 - another secondary Exchange nnimap server that is also not reachable
   apart from at work.  Currently denied manually in the server buffer 

When I do `g' and then `J s' to download new articles into the agent,
it stops with this text in the mini-buffer:
	Error ((error Selecting deleted or non-existent buffer)).  Continue? (y or n) Yes

Anyone have any idea what causes this?  It isn't enough of an error to
trigger a stack trace by doing this:
	(setq debug-on-error t)

Is there another debug variable I should set, maybe?

The error is caught by some condition-case. (setq debug-on-signal t)
helps.
