Luci-app-samba4 broken?

Hi, so I've reflashed, and I held off on installing Samba because of all the problems I've had. But I decided to do it tonight, installed luci-app-samba4 using Luci, and checked the configuration template. It's totally blank, same problem I had last time (this is a fresh install of OpenWRT.) Here's a screenshot:

There was an error message in the install, I can't remember it now, dbus unknown something or other I think. I assume this blank config file means Samba is not going to work, and won't proceed. What do you guys advise?
