Empty list of relays and no details about relays in current circuits
In the recent alpha testing bundles, Colin and I have both confirmed an issue with the Tor network map in Vidalia on all operating systems; when you run TBB for the first time, the list of relays is empty and there are no details about relays in current circuits. After it's launched a second time all of the information appears except platform which remains an empty field on all relays in Vidalia.
The alpha testing bundles ship with Vidalia 0.2.20, Tor 0.2.3.21-rc, and Qt 4.8.1.
