Do not crash the POI search. It ain't made for this. Bad solution.

In Vienna I'ld say we have already about 1/3 of all addresses. It would 
be worthwile. But only if included in the real address search. 
cgpsmapper supports searching for house numbers (and also showing them 
on the map on mouseover like Garmin City Navigator) via address search - 
so in principal the code is available (though with polish documentation).
