I can reproduce this, but oddly it only seems to have gone wrong for
that one thread -- all the other threads in the mailbox seem to be
sorted correctly. I also note that the Summary buffer displays the date
of both messages in the thread as one day earlier than the Date header
in the message itself. So I wonder if there's just something weird about
one or both of the messages that's causing Gnus to handle the date
incorrectly.
When I have a bit more time I'll try to figure out what date Gnus is
trying to use for that thread.
On my personal messages, there is also only exactly one thread placed
in the wrong position. My guess is that there may be something on the
boundary not handled properly during sorting ...
