Geokit and URI Error

Hallo, I have installed geokit and when I use irb to get geocode from google maps everything works fine

irb(main):001:0> require 'geokit' => true irb(main):002:0> location = Geokit::Geocoders::GoogleGeocoder.geocode ('Athens') => #<Geokit::GeoLoc:0x99d7750 @all=[#<Geokit::GeoLoc:0x99d7750 ...>], @street_address=nil, @city="Αθήνα", @state="Αττική", @zip=nil, @country_code="GR", @province="Αθήνα", @success=true, @precision="city", @full_address="Athens, Greece", @lat=37.97918, @lng=23.716647, @provider="google", @country="Ελλάς", @accuracy=4, @suggested_bounds=#<Geokit::Bounds:0x9e97e98 @sw=#<Geokit::LatLng: 0x9e97f10 @lat=37.9439911, @lng=23.6526173>, @ne=#<Geokit::LatLng: 0x9e97ed4 @lat=38.014352, @lng=23.7806767>>> irb(main):003:0>

def update_cities   location = GoogleGeocoder.geocode('Athens') end

from http://localhost:3000/user/update_cities I get the following error URI::InvalidURIError in UserController#update_cities

bad URI(is not URI?): http://maps.google.com/maps/geo?q=Athens&amp;output=xml&amp;key=xxxxxxxx&amp;oe=utf-8
