Took me a while to see, but the difference is in the last line of the client
hello. Your working example has MD5+RSA listed as a TLS 1.2 signature pair
whereas first doesn't.
0302 SHA-224 DSA
0303 SHA-224 ECDSA
0201 SHA-1 RSA
0202 SHA-1 DSA
0203 SHA-1 ECDSA
000F TLS_DH_RSA_WITH_DES_CBC_SHA
0101 (missing from first example) MD5 RSA
0001 TLS_NULL_WITH_NULL_MD5
0130 - 03 02 03 03 02 01 02 02-02 03 00 0f 00 01 01 ...............
0130 - 03 02 03 03 02 01 02 02-02 03 01 01 00 0f 00 01 ................
0140 - 01 .
The trailing 1 is compression.

Subject: client hello difference 1.0.1e vs 1.0.1f
Hi,
Is it possible to make s_client give more detail about the client
hello it sends. A break down covering the RFC structure would be
useful.
struct {
ProtocolVersion client_version;
Random random;
SessionID session_id;
CipherSuite cipher_suites<2..2^16-1>;
CompressionMethod compression_methods<1..2^8-1>;
} ClientHello;
I'm trying to work out what is different between these two connections
(and why one works but the other doesn't):
