[rt-users] NotifyActor - cc to person answering ticket causes extra mail

[Justin C. Sherrill]

I have:

Set($NotifyActor, 1);

set in my RT_SiteConfig.pm.  When a user here is responding to a ticket, and 
puts her own email address in the CC: field, she gets one mail with no To: 
field and her address in the CC: field, and another mail with her address in 
the To: field and no CC:.  It's just a cosmetic problem, since the mail does 
go.  Is this expected behavior, since I have the notification override above?  
i.e. Does anyone else see this?
