Adding SVN to Previously Create Site Fails

When attempting to enable the SVN repository feature in Virtualmin on our dev. system we are receving the following error:

Failed to modify server : virtualmin-svn::feature_setup failed : Undefined subroutine &htaccess_htpasswd::create_user called at /usr/share/webmin/virtualmin-svn/ line 149.

Information about the system:

Operating system Ubuntu Linux 7.10
Webmin version 1.430
Virtualmin version 3.61 (Pro)
Theme version 6.1
Kernel and CPU Linux 2.6.22-14-server on i686

Any assistance would be appreciated.
