[Evolution] IMAP: last message to arrive in a folder is not shown

[John N S Gill <jng renre-europe com>]

I have evolution set up to use IMAP to talk to an exchange server. I
also use the little gnome panel applet to notify me of new mail arriving
on the exchange server.

The little penguin starts dancing when new mail arrives, but it doesn't
show up in evolution.  If a second new message arrives then I get to see
the penultimate message.

If I delete a message from the folder and then expunge messages then I
get to see all messages in the IMAP folder, including the most recent.  

I'm currently using evolution-0.15.99-snap.ximian.200110050808, but this
problem has been around for some time now.

Hope this helps someone track down the problem.. let me know if you want
more info/experiments.

John.
