Sounds about right to me :)

Could you enable ssl-debugging by entering a filename in the 
ssl-protocol-preferences at "SSL debug file"? Are there any
clues in the debug-file? If you need help interpreting, could 
you send the debug-file to the list (or me)?

Just some shortcomings of the decryption-capabilities:
- SSLv2 is not supported 
- Cipher 0x39 (TLS_DHE_RSA_WITH_AES_256_CBC_SHA) is not supported
  by the libraries used by Wireshark and is used for example by firefox
