I'm finally back from traveling and found that this morning Paul pushed a fix to block AEAD ciphers in 3.4.x GnuTLS, citing a fix made a year ago in 3.5.x. Since we can't easily do more on the Emacs side, I agree with the fix and it should resolve the problem for you and other 3.4.x users by avoiding AEAD tests. Sorry this took so long from my side. Thanks Ted
