Navigating to SSL forced subtrees results in misformatted urls.

Steps to reproduce

In my settings/siteacess/mysite/site.ini.append.php I have

[SSLZoneSettings]
SSLZones=enabled
SSLSubtrees[]
SSLSubtrees[]=/member_data

But when I navigate to member_data I get a Kernel (20) Module not found error with the url format like this: https://my.website.com.au/member_data/:/member_data

If I manually enter the url: https://my.website.com.au/member_data it loads into SSL and then exists SSL correctly.

After a little more testing I then added an extra ssl subtree: SSLSubtrees[]=/support interestingly this url is totally ignored and no SSL is forced at all.
