You're getting that error probably because something is hitting your site with a blank Useragent. This is fixed in the next version that's currently in testing and will hopefully be out in beta next week.

Has this regressed? I'm seeing this exact same exception: blank user agent, NullReference somewhere in the ActiveDirectory module for a request hasn't even logged in yet. The Active Directory module is installed and in use here. Currently on 7.0.6
