 This looks like it might be related to #792 (or be in fact the same bug),
 but 792 is supposed to be fixed in libevent 1.4.12.

 The log as displayed by Vidalia is this:
 {{{
 Sep 25 01:18:35.311 [Notice] Tor v0.2.2.15-alpha (git-eba3f37f17a2af4f).
 This is experimental software. Do not rely on it for strong anonymity.
 (Running on Windows XP Service Pack 2 [workstation])
 Sep 25 01:18:36.405 [Warning] Warning from libevent: evsignal_init:
 socketpair: No error
 Sep 25 01:18:36.405 [Notice] Initialized libevent version 1.4.14-stable
 using method win32. Good.

 Sep 25 01:18:46.402 [Notice] OpenSSL OpenSSL 0.9.8k 25 Mar 2009 [9080bf]
 looks like it's older than 0.9.8l, but some vendors have backported
 0.9.8l's renegotiation code to earlier versions, and some have backported
 the code from 0.9.8m or 0.9.8n.  I'll set both SSL3_FLAGS and SSL_OP just
 to be safe.
 Sep 25 01:18:47.056 [Notice] We now have enough directory information to
 build circuits.
 Sep 25 01:18:47.056 [Notice] Bootstrapped 80%: Connecting to the Tor

 first hop.
 Sep 25 01:18:48.805 [Notice] Bootstrapped 90%: Establishing a Tor circuit.
 Sep 25 01:18:51.599 [Notice] Tor has successfully opened a circuit. Looks
 like client functionality is working.
 Sep 25 01:18:51.599 [Notice] Bootstrapped 100%: Done.
 }}}

 No Windows or other firewall running according to the user. It looks like
 Vidalia loses connection to the Tor in the process, too.

 This could be a bug with the way we built the bundle, though I just tried
 it on win7 and it worked fine, or a libevent bug, or a Tor bug; or all of
 the above. Ideas?
