Bug Description
I just updated a couple of server from 5.2.4 to 5.5.23. Now when I try to connect to them through mysql-proxy (using mysql CLI) I get:
ERROR 1043 (08S01): Bad handshake
the mysql-proxy (0.8.2) log shows:
2012-04-15 17:49:28: (debug) [network-
connecting to the 5.5.23 servers directly works fine. Also some client libraries seem to work (my local php installation for example can connect fine through the proxy)

The problem exists in latest releases of 5.2, 5.3, 5.5.
5.1.62 works all right.
In 5.2 line, it started between 5.2.7 and 5.2.8 -- 5.2.7 works fine, 5.2.8 does not.
MySQL 5.5.21 works okay.
We looked into a similar problem some time ago, see bug #904097. That time it was deduced that starting from 5.2.8, server applies stricter requirements to handshake packets and does not accept what it finds malformed, as it did in versions 5.2.7 and earlier. Manifestation of the problem is similar to what is described here, so it may be the same, or have the same root cause.
Bug #904097 was closed because the problem had already been fixed on the client side. This time, the client is mysql-proxy of the latest version (I tried the binary package), so it's probably hard to expect that it will be fixed there.
