It's a bug but usually harmless. Nos says "hello I've got some news 
for group such and such", demon says "send it" so Nos does. Then Nos 
says "hello I've got some news for group <blank>" so demon says "501 
USAGE". This happens for each and every article.

Fortunately the RFC states that an erroneous GROUP command should 
leave the last valid settings in effect and demon implement this so 
when Nos sends the article demon accepts it on the basis of the 
previous valid GROUP.

I'm not sure of the exact cause.
