The list actually avoids sending you email when someone does a reply
all. Those are sent directly from the person who did a reply all. There
are a few ways to deal with this. Here is one:

If you log in to the gnu mailman interface at
lists.gnu.org/bug-gnuzilla, and change you person options to turn off
the "nodup" feature, then when someone does a reply-all, the list will
continue to send you an email. Then you will always get a an email with
the list-id header. Then, you can configure your email client to discard
the duplicate that is from @debbugs.gnu.org but does not have any
list-id header.
