duplicate articles

Hi

First thanks for this great program. I used it for more than a year and it
simply worked :-)

Now my problem:
Recently I set up my new router and put sn 0.3.5 as the latest version on
it. But now it is the second time that I have news articles, which appear
more than 5 times (with same headers). This does not affect all articles in
a group, sometimes there are articles, which appear only once (like they
should).

It seems, that this problem does not affect local groups, and it doesn't
seem like a problem of the upstream news server, because I have 2, and
groups from both show this behaviour.

A downgrade to 0.3.4a does not solve my problem.
I have debian woody and a self-compiled sn.


Thanks
  Jörg
