We can't see the full headers in the archive, or
at least I can't see
any way to access them, but in my copy, it also seems to have no mystery
header.
I believe that whatever caused the problem, poking at it with a stick
has caused it to go away.
I declare the problem fixed, until it reoccurs :-)
I can only imagine that I might have used an old template by mistake, and
maybe that contained the problematic reference lines.
While trying to track down the problem, however, I did some housecleaning, and
got rid of the old stuff that I never (or at least thought I never) use any
more. So if it was in an old template, it's gone now.
Let's hope this is the end of it. Thanks everybody for their patience.
Now I am trying to get Konversation to run over Tor using their onion links. I
haven't had time to get the IRC going.
