Google Maps API cannot process one specific address - google-maps

Question

We have a working Google Maps API (V2) module working correctly on our custom made CMS.
I cannot figure out why but this code seems to be having troubles processing one specific Address. What's weird is that the address can be found normally on Google Maps.
Here are two examples, one address that works perfectly and the address that Google Maps API cannot find :
Working Address : via Zups 2, 7013 Domat/Ems
<script>
initialize( "googlemap-viazups17013domat/ems", "via Zups 2 7013 Domat/Ems" )Marly" )
</script>
working HTML output (cleaned up)
Unworking Address : via Zups 1, 7013 Domat/Ems
<script>
initialize( "googlemap-viazups17013domat/ems", "via Zups 1 7013 Domat/Ems" )
</script>
non Working HTML output (cleaned up)
Also note that if I change the address to display Number 2 of the same street it works! But Number 1 never works.

Edit :
Here is the initialize function :
function initialize( div, address ) {
var geocoder;
var map;
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(-34.397, 150.644);
var myOptions = {
zoom: 15,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP,
scrollwheel:false
}
map = new google.maps.Map(document.getElementById( div ), myOptions);
//map.disableDragging()
if (geocoder) {
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
} else {
alert("Impossible de localiser " + address);
}
});
}
}
