After "GROUP"ing not even one article was fetched. Therefore there can't
be improper escaping of leading dots, I think.

Having 3 or 4 servers in my leafnode/config, I appended "-S
news.gmane.org". The output is quite more strange than the above:

Using netcat I found out, that 2 of these article numbers are "wrong".
|# cat news.gmane.org
|GROUP gmane.linux.gentoo.user.german
|ARTICLE 27321
|ARTICLE 27323

|423 Bad article number
|423 Bad article number
|205 .
Articles 27320, 27319, 27322, 27324 and 27325 are sent as expected.
The error occurs also while sending just *one* "ARTICLE 27321" without
any more text after. Even without "QUIT" (manually killing of netcat
necessary) the same output from the server occurs.
According to RFC 977 an expected answer to "ARTICLE" is 423 (no such
article in this group). The text being sent by Gmane may not be as
precise as suggested by RFC 977, but the text should not be parsed by
the client. So the output seen in the log is not really correct:
|Wrong reply to ARTICLE command: "423 Bad article number"

I suspected this, but I'm not sure any more.

The servers before were without any special notice. ("store: no valid
newsgroups" not counted)
Then fetchnews connected to news.gmane.org. After reloading the
newsgroups list (8681 newsgroups) and complaining about name conflict
(gmane.comp.gnome.apps.Dia vs. gmane.comp.gnome.apps.dia) it got the
descriptions without any further notice. fetchnews loaded some
control.newgroup (store: no valid newsgroup), got some "real" groups and
then ...

Hope this helps...
