Validate virtual servers fails

The latest version of the module fails to validate domains.

I get this error:

Beginning validation of selected virtual servers. Any problems found will be shown in red ..

HTTP/1.0 500 Perl execution failed Server: MiniServ/0.01 Date: Fri, 19 May 2006 20:27:37 GMT Content-type: text/html Connection: close
Error - Perl execution failed

Quantifier follows nothing in regex; marked by < -- HERE in m/* < -- HERE / at /usr/libexec/webmin/virtual-server/feature-spam.pl line 166.

You can see this yourself on the demo server: https://demo.virtualmin.com:10000/

(root/demo is the login)

You can get ssh access if you hit 172.20.0.2 while logged into virtualmin.com.
