broken start of header - cant find the problem

I updated some software of the server, and ever since the posts to sn get 
broken.

First i just noticed the subject missing (or the from line - depending on the 
client), but after looking carefully i noticed that it's actually a missing 
End-Of-Line at the start of the header:

the generated entry in /var/spool/news/test/ looks like this
----
POST: X-sn-Newsgroups: testESCEFrom: [...]
Subject: Test
Date: [...]
User-Agent: [...]
----

Somehow i get a "Esc-E" instead of a Endline

I allready tried everything i could think of. recompiled everything i could 
think that sn uses, sn itself, deleted and recreated the newsgroup, and so 
on...

Any idea what might have gone wrong?
Are there incompatibilities with some software?

Worf

PS: what happened to the bug that sngetd creates Zombie processes?
