Malformed header causing SIGSEGV?

I am running inn-1.7.2+insync under Linux. Yesterday, my innd started
 dying with a SIGSEGV every time a particular article was fed to it. 
The feed is coming from a transit server running diablo. Here are the 
headers of that article:

-- begin --
From: michael at (michael)
Newsgroups: soc.culture.malaysia
Subject: Re: BN is the Future
Distribution: ,
Message-ID: <942925094.1792snx at>
References: <3832ca65.8704867 at>
Date: Thu, 18 Nov 99 11:38:14 GMT
Organization: Penang, Malaysia
Lines: 303
-- end --

Notice the malformed Distribution header. Could parsing of it be
the problem?

Also note that I do have a list of acceptable distributions in
the ME newsfeeds entry so innd would want to work with the
Distribution header in my case.

I realize inn-1.7.2 is probably no longer supported, but since I 
saw a post in today from an inn-2.2 user who
reported a similar problem, I thought it might be worth mentioning.
If this is a bug in innd, it could be used as a nasty DOS attack.
