[mkgmap-dev] Address search in mapsource fails to find some streets

Just playing around with mapsource using the street search feature and noticed that some streets don't show up in the search. For example, in the GB map, I can select "Well Street" from the select street dialog but when I ask it to find that street, it says nothing found. Other streets in the same locality are found OK. It's weird that it knows about the street enough to put it in the dialog but then can't actually find any streets with that name. Is this a known issue? Mark
