Hi,
I am using kamailio-3.3.2 on Ubuntu 11.04 x64 and when trying to connect via TLS from my Yealink phone kamailio crashes with the following backtrace:

Loaded symbols for /lib/x86_64-linux-gnu/libnss_files.so.2
Core was generated by `/opt/kamailio/sbin/kamailio'.
Program terminated with signal 11, Segmentation fault.

The manual I am following is http://www.kamailio.org/dokuwiki/doku.php/tls:create-certificates
