I've been able to reproduce this problem now with a current sid chroot.
Lintian is correct; the man pages really aren't compressed:

.SH DESCRIPTION
This program reads access request logs from kernel and writes to specified location.

It looks an interaction between dh_installman and man --recode is at
fault.  Upstream installs the man pages already compressed, but then
dh_installman does:

        man --recode UTF-8 ./ccs\-notifyd\.8\.gz > ccs\-notifyd\.8\.gz\.new
        chmod 644 ccs-notifyd.8.gz.new
        mv -f ccs-notifyd.8.gz.new ccs-notifyd.8.gz

for each man page.  man can read the compressed man page just fine, but
writes out an uncompressed man page, and they're not then recompressed
because they still have *.gz extensions.

I'll reassign this bug to debhelper.
