some articles cannot be found with IMAP

[Seb <spluque@gmail.com>]

Hi,

I use an IMAP server defined like:

(setq gnus-select-method
	     '(nnimap "myself"
		      (nnimap-address "my.imap.server")
		      (nnimap-stream ssl)))

I also access the server with another client (Kmail).

When I delete from a given box or move articles between boxes in Kmail,
then Gnus gets confused about what happened and can no longer find
articles that weren't touched at all.  For example, suppose there are
these messages in INBOX:

1
2
3

If I get into INBOX in Kmail and delete message "1", Gnus correctly
understands this message doesn't exist so no longer shows it in the
summary buffer, but does list "2" and "3" there.  However, if I select
"2" *or* "3" I get "No such article (may have expired or been
canceled")".  These articles are of course there, as I can read them in
the server and in Kmail, and nothing was done to them.  It seems as if
Gnus has gotten confused about the sequence of articles in the server.

I've tried M-g'ing and M-c'ing the group, and restarting Emacs/Gnus, but
that doesn't change anything.  Any advice on how to correct this would
be appreciated.

Cheers,
