Package: exim4-daemon-heavy
Version: 4.63-11
When I try to send authenticated email through my server using TLS,
the server crashes.
libgnutls13 version is 1.4.4-3
Reverting to 1.4.2-2 solves the problem.
Feel free to reassign this problem to gnutls13 if the problem's
really there.
Here's an strace:
