It seems that some unknown cipher suite is used:

dissect_ssl3_hnd_srv_hello can't find cipher suite 39 

39 looks like TLS1_CK_DHE_RSA_WITH_AES_256_SHA 
is it possible?

Thanks for the reply.  I have no idea why it isn't decoding.  I've
attached the whole ssl debug file.  Any clues?  What else can I do to
help debug this?

Thanks
