Your bugreport in Debian shows the cause https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=835587 I have just rebuilt GnuTLS with the necessary patches (unfortunately you need four patches on top of GnuTLS 3.5.3 to apply cleanly) and will submit the patch to the BTS asap. Downgrading gnutls to http://snapshot.debian.org/package/gnutls28/3.5.2-3/ should fix your problem if that bug is correct. Bernhard
