Title: bugId: 95249 - try to avoid using a fake "empty" title 

This will go out with the release tomorrow and I will check the MultiWikiFinder to see if the problem is still happening. There may be other locations where the same problem happens. I can't think of a better solution for the root problem right now. There is no case I can think of where passing around a fake title object called "empty" is the right thing to do, but if I try anything else, it causes a fatal error.
