Guacamole 0.9.9 VNC disconnect immediatly : segfault

Hi,

I am not able to use VNC connection with Guacamole 0.9.9. I tested multiple Install on VM Centos and Ubuntu without success.
(My last install is on a Ubuntun 16.04 with this script : http://chasewright.com/guacamole-with-mysql-on-ubuntu/)
VNC servers are TightVNC or UltaVNC.

Anyway, VNC disconnect immediatly, issue is always a segfault, check out my syslog :

Hi Jérémy,

Can you confirm whether this segfault still occurs with a copy of guacamole-server built from recent git?
