The pseudo-article is only displayed in one of the following conditions:

1) the directory for the group (i.e.  /var/spool/news/name/of/newsgroup)
   does not exist

2) the directory for the group exists, but there is no .overview file

3) the directory for the group exists but the article number requested
   does not AND the article number requested is the only article in the
   group.

The third condition should strike if a newsgroup is unsubscribed and
all articles are expired.
