Comment 5 for bug 346513

We are now detecting whether people are exporting the interface on the bus by looking at the introspection data and seeing if they say they are. This fixes most of this problem, but there are still some services that are blocking their introspection data. This is incorrect. D-feet also has this problem and causes the auth.log entries on these servers. I'm marking this fix committed because at this point I think that *we're* doing it correctly. The rest of the fix is on their side.
