Comment:

 The behaviour of the website has changed with respect to interpolation
 points. You can see on Nominatim's website that it returns the correct
 coordinates for the address:

 http://nominatim.openstreetmap.org/search.php?q=9+Heriot+Row+Edinburgh+UK&polygon=1

 In the XML, Nominatim returns the correct coordinates as well but also
 returns the OSM object id of one of the interpolation points because it is
 the closest to the address. It does initially zoom in on the right
 coordinates but then moves to the interpolation point (at least when it is
 outside the viewport), which is admittedly rather unexpected.

 I'm not quite sure what's the best solution here. Nominatim simply could
 stop returning an OSM object for interpolated addresses. I believe the
 website will then do the right thing and put a marker on the coordinate.
 However, I'm reluctant to do that as there might be applications that rely
 on the current behaviour.
