Hi,

Every once in a while Gnus (as shipped with GNU Emacs 19.34b) sorts
the summary buffer weirdly as shown below.  Note the two lines with
the subject 'Re: Monotheism vs Polytheism in Paganism' appear to be
sorted badly out of order.  From their scores they should be near the
bottom of the buffer, not stuck in with the zero-scored articles.
This occurs ONLY with articles that have 'Re:" on the front of them
and happens in almost all groups at least occasionally.

Has anyone else seen this?  It has been happening to me for a long
time now and has finally reached my irritation threshold.
