Adding SSL to my website - apache

Question

I have the following virtual hosts config:
listen 80
listen 443
servername "example.com"
serveradmin "email#example.com"
namevirtualhost *:80
namevirtualhost *:443
directoryindex index.html index.php
options -indexes -multiviews +followsymlinks
<directory /Volumes/dev1/http>
allowoverride all
</directory>
<virtualhost *:80 *:443>
servername example.com
serveralias www.example.com
documentroot "/Volumes/dev1/http/example"
rewriteengine on
SSLCertificateFile "/Volumes/dev1/ssl/_ssl-cert.crt"
SSLCertificateKeyFile "/Volumes/dev1/ssl/_ssl-privatekey.crt"
SSLCertificateChainFile "/Volumes/dev1/ssl/_ssl-csr.crt"
</virtualhost>
Of course example.com is just an ... example.
All is well if I access http://example.com, but if I try to access the HTTPS version I get
Safari can’t open the page “https://example.com/” because Safari
can’t establish a secure connection to the server “example.com”.
The _ssl* files are all in place and running httpd -t from Terminal returns Syntax OK.
What am I doing wrong? Thanks!

This what I'm using (only the vhosts section), omitting the FCGID, suexec and PHP specific parts:
<VirtualHost *:80>
ServerName example.com
DocumentRoot "/var/www/example.com/htdocs"
<Directory "/var/www/example.com/htdocs/">
Options -Indexes
AllowOverride All
Order allow,deny
Allow from All
</Directory>
ErrorLog "/var/www/example.com/error.log"
CustomLog "/var/www/example.com/access.log" combined
</VirtualHost>
<VirtualHost *:443>
ServerName example.com
DocumentRoot "/var/www/example.com/htdocs"
<Directory "/var/www/example.com/htdocs/">
Options -Indexes
AllowOverride All
Order allow,deny
Allow from All
</Directory>
SSLEngine on
SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL
SSLCertificateFile /etc/apache/ssl/example.com.crt
SSLCertificateKeyFile /etc/apache/ssl/example.key
SSLCertificateChainFile /etc/apache/ssl/gd_bundle.crt
ErrorLog "/var/www/example.com/error.log"
CustomLog "/var/www/example.com/access.log" combined
</VirtualHost>
