BUG?? - BIND Module Trouble

[Graham R. <gr...@av...>]

Whenever I specify another file for adding new zones under the bind 8
modules's options, then create a new master zone, I get the following error:

HTTP/1.0 500 Perl execution failed Server: MiniServ/0.01 Date: Fri, 12 Oct 2001 18:52:18 GMT Content-type: text/html Connection: close 

Error - Perl execution failed

Can't use an undefined value as a HASH reference at /usr/libexec/webmin/bind8/edit_master.cgi line 28.

When I change the module's config back to add the new zone to named.conf, the
zone is created without a hitch. 
I'm using webmin 0.88 on RedHat 7.1
