need another vidalia stable release before tbb with tor 0.2.3 can go stable
https://gitweb.torproject.org/vidalia.git/tree/HEAD:/changes currently shows change files for bugs #6482 (closed), #6568 (closed), and #6601 (closed).
All three of these are bugs that users keep reporting. We should make a new Vidalia stable, and a new TBB-alpha to test it, before we can move TBB-stable to the Tor 0.2.3 tree.
