"Apply Zone" missing for server owners

I am running the following:
OS: Debian Linux 4.0
Webmin version: 1.450
Virtualmin version: 3.65.gpl GPL
Theme version: 6.6

When a virtual server owner updates their DNS zone it appears that they are unable to publish the changes because the "Apply Zone" link appears to be missing.

I have been able to work around this problem by creating the attached patch to /bind8/bind8-lib.pl.
