Comment (by nickm):

 I've been staring at the logs, and I have a new idea:
 {{{
 Nov 22 11:37:06.000 [info] TLS error while handshaking with [scrubbed]:
 wrong version number (in SSL routines:ssl3_get_record:SSLv3/TLS write
 client hello)
 }}}

 This is an error I might expect to see if we had a mismatched pluggable
 transport: if we weren't using one when we were supposed to, or if we were
 using the wrong one and the transport didn't notice.

 I've made a new branch `ideas_for_24367` to try to track down this
 possibility.  It doesn't make any changes: it just adds new logs to 0.3.2
 to keep track of our transport plans, and the bridge addresses we think
 our guards have.  Could you generate info-level logs for the failing case
 using this branch?
