correction:  it seems that Vidalia now proxies its geoip queries, so
your IP address is not exposed that way.  Quoting from
http://trac.vidalia-project.net/wiki/FAQ:

> Does Vidalia "phone home"?
> 
> No, not really. Vidalia 0.0.5 added the network map feature, letting
> you see where in the world your traffic is going. To be able to map
> Tor server IP addresses to approximate geographic locations on the
> map, we use the GeoLite City database from MaxMind. Unfortunately,
> the database is around 24MB and shipping it alongside the Vidalia
> binary would be unreasonable. Consequently, we host the database on
> our servers and created a small perl script interface to it, allowing
> us to query the database via standard HTTP GET or POST requests.
> 
> All communication between Vidalia and our servers is done over Tor,
> so our servers do not know who is making the requests. Additionally,
> no identifying information is included in the requests. Of course,
> you can verify this by looking at the source code, such as
> geoipresolver.cpp and torsocket.cpp. We also have a specification for
> the format of our geographic information requests and responses.
