I kept getting errors when I assumed that.  I'm not sure what's the
cause, but headers are often missing in the newsgroup-data.  It
doesn't show up often, maybe 5% of the time, and I couldn't find a
pattern to it (except that it was repeatable when you re-entered the
group).

Maybe it's threads-related?  I don't know.  Anyhow, if you need me to
show you examples of this problem I can, but I can't trace the root
cause of why the headers are nil.  I tried that and everything looked
OK last time.

Oh, there was a very recent fix for gnus-dup-unsuppress-article which
dealt with this also, because the mail header would be nil there too.
