read marks reverting occasionally

[Alex Schroeder <alex@gnu.org>]

I reported this as a bug before leaving for holidays, and now it is
getting worse, I think.

Here is what my Group buffer looks like right now:

[ Gnus -- 7175 ]
       2: nnml:mail.spam 
       1: nnml:drafts 
  [ misc -- 7172 ]
       136: nnml:mail.misc 
         3: nnml:mail.wilhelmtux 
         1: nnml:mail.wilhelmtux.admin 
        78: nnml:mail.wsis 
       152: nnml:mail.bytes4all 
*        0: nnml:mail.family 
*        0: nnml:mail.friends 
... etc.

When I start Gnus, however, nnml:mail.misc will often be listed as

*        0: nnml:mail.misc

When I hit enter, I am asked how many mails I want to see, defaulting
to a number between 500 and 1000 (there are a of 4000 to 5000 mails in
this group).  I accept the default and the summary buffer is shown.
First, a few dozen ticked messages, then a number of unread messages.
The list of unread messages seems to correspond to the the time when I
came back from my holidays (2003-07-29); I always mark some as read
and move some into nnml:mail.spam.  I even did a catchup all (`c')
yesterday.  Nevertheless, today the situation is the same.  When I
quit the mail.misc summary buffer, I get shown the group buffer where
mail.misc is listed with 100 - 200 messages (as in the example above).

In short, my read marks seem to get lost from time to time.

Any idea of how I could start debugging this?  Has nobody else noticed
this?  I upgraded from CVS as soon as I noticed the problem again
after my holidays, hoping that it had been fixed in the mean time.
But as far as I can tell, this is a problem with my config that has
been going on for several weeks by now.

Anybody interested in my .gnus file?

Alex.
