Hmm, the output mail-header-subject returns looks always a
decoded subject.  Raw headers gathered in the " *nntpd*" buffer
are decoded when building the value of gnus-newsgroup-headers as
far as I know.

Aren't there ticked articles in the group?  In such a case, `A T'
ignores articles newer than the last article listed in the
summary buffer.  Although I don't understand why it does so, the
possible workaround is to set the gnus-refer-thread-limit
variable as t, not a number.  If it is not effective, something
exceeding my imagination may have occurred.
