dovecot - Sep 2009 - Apparent corruption of dovecot.uidlist

I have been using Dovecot for about three years, and am currently using 
version 1.0.7 under CentOS.  One of my users can no longer access his Inbox, 
although he can read mail in other folders.  After a fair bit of log-viewing 
and looking for clues it suddenly began to make a sort of sense.  The error 
message in the logs is

Error: IMAP(david): 
unlink(/home/david/Maildir/cur/cur:2,ST) failed: Is a directory

Eventually I came to /home/david/Maildir/dovecot-uidlist and compared it with 
my own.  The second line in the problem account file is 'cur:2,ST.

I backed up the file, then deleted that line.  Sure enough, I could then open 
the messages.  Unfortunately, when I close KMail I saw the line
'cur:2,ST'
added to the end of dovecot-uidlist, and of course I'm back with the error.

Can someone please explain to me what is causing this, and how I can correct 
it?  Thanks

Anne

There a thread here discussing this error:

http://www.dovecot.org/list/dovecot/2009-February/037280.html

Bottom line:

"This means that "new" and "cur" directories were
created to either
Maildir/cur/ or Maildir/new/ and since there should be only messages
Dovecot tried to handle them as files/messages. Dovecot didn't create
those directories. You probably misconfigured some other program at
some point which created those (or you did it manually)."

So, if you have /cur/cur and /new/new directories, delete the second
level ones...

Upgrading would probably be a good idea while you're at it... 1.0.7 is
very old...
