Hi,

when I try to start a session with x2goclient (or Pyhoca-gui), the client crash just after login.
x2goclient create connection to the server :
Dec 17 22:26:11 marc-P55-UD3R sshd[13752]: Accepted password for marc from 192.168.1.13 port 52967 ssh2
Dec 17 22:26:11 marc-P55-UD3R sshd[13752]: pam_unix(sshd:session): session opened for user marc by (uid=0)
Dec 17 22:26:11 marc-P55-UD3R systemd-logind[869]: Removed session c1.
Dec 17 22:26:11 marc-P55-UD3R systemd-logind[869]: New session 21 of user marc


Then x2goclient crashes. gdb give the following trace:
x2go-INFO-1> "Starting x2goclient..."
x2go-INFO-4> "Translator: :/x2goclient_fr_fr installed."
x2go-INFO-5> "Translator: :/qt_fr_FR installed."
x2go-INFO-3> "Started  x2goclient."
x2go-INFO-8> "Starting connection to server: 192.168.1.11:22"

This is apply to x2goclient v. 4.0.3.1 both amd64 & i386 (Qt 4.8.6)
and x2goserver v 4.0.1.18-0~949~ubuntu14.04.1 - amd64
