[Mailman-Developers] blank Cc header?

[Dallas Bethune]

One of our users reported that Mailman (2.1.5) sometimes adds blank  
Cc headers and he sent in a link to this patch to the debian version  
that claims to fix it:

20cc&rnum=2#8c4d983e785d5548


I searched around on sourceforge and the mailman faq wizard and  
google and didn't see any other mention of it.  Does anyone know  
about this?  Is there an existing patch outside of Debian?
