For me it looks as some bug in gnutls...
# dpkg -l 'libgnutls*' | fgrep ii
ii libgnutls-dane0:i386 3.7.0-5 i386 GNU TLS library - DANE

ii libgnutls30:i386 3.7.0-5 i386 GNU TLS library - main
runtime library
I plan to overcome it with `hosts_avoid_tls'. But I'll keep this mail
in queue some time, waiting for additional questions (if any).
