So I can only see this bug when I'm not connected to the Internet (and I added that to the reproduction steps above). If you are sure you saw this when connected, perhaps there are two bugs here. But working on the non-connected bug, obviously, you wouldn't expect lots of London results. We'll match the tiny database we ship with, but it may not have London (I think it doesn't, in fact).
