I am sorry.

Correction: there is no phantom packet.  GnuTLS returns the
"GNUTLS_E_UNEXPECTED_PACKET_LENGTH -9    /* GNUTLS_A_RECORD_OVERFLOW */"
error code when there is an EOF because of abrupt client disconnect.

So much of my analysis is bonkers, but there's still an issue.  NSS
*can* set up a client connection to GnuTLS 2.8 but not 2.12,
disconnecting after receiving server_hello_done.

Any help / guidance appreciated.

Thanks,
