Ssl – Apache VirtualHost with SSL Not Found

I setup 3 virtual hosts on port 80. Everything is fine.
Now I would setup the SSL version of these virtual hosts. All works except the main DocumentRoot.

Listen 80 
ServerName www.mydomain.com
NameVirtualHost *:80
NameVirtualHost *:443
<VirtualHost *:80>
    ServerAdmin webmaster@example.com
    DocumentRoot /home/someone/www/work
    ServerName work.example.com
    <Directory /home/someone/www/work>
    Options +FollowSymLinks
    AllowOverride All
    Order allow,deny
    allow from all
    </Directory>

</VirtualHost>

<VirtualHost *:80>
    ServerAdmin webmaster@example.com
    DocumentRoot /home/someone/www
    ServerName www.example.com
    <Directory /home/someone/www>
    Options +FollowSymlinks
    AllowOverride All
    Order allow,deny
    allow from all
    </Directory>
</VirtualHost>

<VirtualHost *:443>
    ServerAdmin webmaster@example.com
    DocumentRoot /home/someone/www/work
    ServerName work.example.com
    SSLEngine on
    SSLCertificateFile /home/someone/ssl-certs-keys/c1.crt
    SSLCertificateKeyFile /home/someone/ssl-certs-keys/c1.key
    SSLCertificateChainFile /home/someone/ssl-certs-keys/c1.i.crt

    <Directory /home/someone/www/work>
    Options +FollowSymLinks
    AllowOverride All
    Order allow,deny
    allow from all
    </Directory>

</VirtualHost>

<VirtualHost *:443>
    ServerAdmin webmaster@example.com
    DocumentRoot /home/someone/www
    ServerName www.example.com
    SSLEngine on
    SSLCertificateFile /home/someone/ssl-certs-keys/c1.crt
    SSLCertificateKeyFile /home/someone/ssl-certs-keys/c1.key
    SSLCertificateChainFile /home/someone/ssl-certs-keys/c1.i.crt
    <Directory /home/someone/www>
    Options +FollowSymlinks
    AllowOverride All
    Order allow,deny
    allow from all
    </Directory>
</VirtualHost>

Now, no problem if I connect to www.example.com, work.example.com, https://work.example.com. The only problem is that when I connect to https://www.example.com, I get The requested URL / was not found on this server".

If I add somewhere in httpd.conf DocumentRoot /home/someone/www the pages there are loaded… Why, for 443, I have to add DocumentRoot, and why the VirtualHost for the main domain is not read.

[EDIT]

As for a comment, if I type httpd -S

VirtualHost configuration:

wildcard NameVirtualHosts and _default_ servers:
*:443                  is a NameVirtualHost
         default server www.mydomain.com (/etc/httpd/conf.d/ssl.conf:74)
         port 443 namevhost www.mydomain.com (/etc/httpd/conf.d/ssl.conf:74)
         port 443 namevhost work.mydomain.com (/etc/httpd/conf/httpd.conf:1074)

Why the default server points to ssl.conf and not httpd.conf?
