Thanks, this is Hans' work (IIRC with Fabien's help), I haven't used gb.map

Tests/FMain.class which seems to use French GoogleMaps.

This seems to be a bug in gb.map. The Geo class is certainly in gb.map and
does some math (involving a logarithm) in line 19.

I think as long as the URL format is known, this can be done in an instant,
but I can't get it to work here... Also I need to head to lunch :-)
