[mkgmap-dev] internal error: found no housenumber road

While processing Australia I get several warnings of the form:

SEVERE (HousenumberGenerator): 51690125.o5m: internal error: found no 
housenumber road for interpolated house 
http://www.openstreetmap.org/?mlat=-37.782001&mlon=144.959382&zoom=17

Looking at that area in JOSM, I see addr:interpolation lines next to a 
footway without a name, connecting houses with addr:street=Royal Parede, 
and a primary road named Royal Parede some 20 m away from the 
addr:interpolation lines. I guess mkgmap searches for street name in the 
footway (which doesn't have a name) instead of in the Royal Parade road, 
and thus it fails to assign housenumbers.
