Clone site misses CA certificate

If I have a site with SSL enabled, and I clone it to a new site with a different domain name, the cloned copy is missing the ssl.ca file in the home directory.

However the ssl.cert and ssl.key file are properly created.

This causes an error in the apache config for the new site:
SSLCACertificateFile: file ‘/home/sitename/ssl.ca’ does not exist or is empty

And at that point apache ignores any future configuration changes (and will fail to start if the server is restarted).

I see that it creates a new certificate (probably because the existing certificate doesn’t match).

I think this causes the ssl.ca file to be “lost”, however the apache configuration remains.

This is using the latest version of Virtualmin/Webmin 5.02/1.795 on Ubuntu 12.04.

Can anyone see this behaviour?

Thanks,
Brad.
