Firefox And An Intermediate Cert

I had to reinstall a Verisign cert last week. After cleaning out a mess of old certs, keys and csr's I finally got the thing to install properly.

However, I get a "Website Certified by an Unknown Authority Error in Firefox".

Everything including the intermediate crt is installed correctly as far as I can tell and I get no error in any version of IE.

Here from the httpd.comf file:

Code:
<IfDefine SSL>
<VirtualHost IPADDRESS:443>
DocumentRoot /home/myuser/public_html
ServerName www.mysite.com
UserDir public_html

User myuser
Group mygroup
ScriptAlias /cgi-bin/ /home/myuser/public_html/cgi-bin/

SSLEnable
SSLCertificateFile /usr/share/ssl/certs/www.mysite.com.crt
SSLCertificateKeyFile /usr/share/ssl/private/www.mysite.com.key
SSLCACertificateFile /usr/share/ssl/certs/www.mysite.com.cabundle
SSLLogFile /usr/local/apache/domlogs/www.mysite.com-ssl_data_log
CustomLog /usr/local/apache/domlogs/www.mysite.com-ssl_log combined
SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown
</VirtualHost>
</IfDefine>

The key matches the cert, and the cabundle is directly from Verisign.

Has anyone had a similar problem with getting a Verisign or other intermediate cert to work properly? I've reissued the thing twice and so far nothing has changed. It's like the intermediate cert isn't being sent even though it is installed.

When viewing the cert in firefox the Certificate Hierarchy only shows my domain. In internet explorer is shows Verisign Class 3 Public Primary CA -> Verisign Class 3 Secure Server CA -> My domain.
