archives are not threaded across months

[Kamaraju Kusumanchi <kamaraju@bluebottle.com>]

Hi all
    I was browsing the d-u archives recently and found a weird behavior. Say I 
go to http://lists.debian.org/debian-user/2006/10/msg03693.html
In the bottom of this page where it says "Next by thread", the link points to 
http://lists.debian.org/debian-user/2006/10/msg03708.html . Once I go to this 
second link, at the bottom of the page there is no "Next by thread" link. 
However, the actual thread does not end there. The next message in this 
thread is http://lists.debian.org/debian-user/2006/11/msg00050.html . Why are 
the archives not threaded across months? Is this a bug which should be 
reported?

    May be I am missing something very trivial here. Any help is appreciated.

thanks
raju
