2.2.9-10+lenny8 upgrade SSL not working after update

[James Sasitorn <james@sasitorn.com>]

I am running Lenny, and upgrading from 2.2.9-10+lenny4 to 2.2.9-10+lenny8 and encountered an error with my SSL configuration in the update. My installation uses apache2 configuration files.. and this is the first time an upgrade has broken a working installation (with no obvious error message). 

My HTTP named virtual hosts work fine. The secure site works fine when SSL is disabled as well. So I figure there is some configuration file change in the newer version. I found a couple posts from about a year ago mentioning something similar, but I wasn't quite sure what the exact cause (since there are no error messages) is and how I would fix it. Below are some of the pertinent config files. Names and addresses changed...

/etc/apache2/ports.conf
--------------
NameVirtualHost 10.0.0.10:80
Listen 10.0.0.10:80
Listen localhost:80
<IfModule mod_ssl.c>
    Listen 10.0.0.20:443
</IfModule>
--------------

/etc/apache2/sites-enabled/secure.site.com
-----------------
<VirtualHost 10.0.0.20:443>
   DocumentRoot /www/site.com
   ServerName secure.site.com
   SSLEngine on
   SSLCertificateFile /usr/lib/ssl/certs/secure.site.com.crt
   SSLCertificateKeyFile /usr/lib/ssl/private/secure.site.com.key
   BrowserMatch "MSIE [56]\." nokeepalive

   <Directory "/www/secure.site.com">
      Options Indexes FollowSymLinks
      AllowOverride All
      Order allow,deny
      Allow from all
   </Directory>

</VirtualHost>
-------------

Any ideas?

Thanks,
James
