[X2Go-Dev] Bug#623: x2goserver update to 4.0.1.16 breaks x2go

[Babutzka, Martin (EKP)]

Package: x2goserver
Version: 4.0.1.16-0~935~ubuntu14.04.1

After the apt update to x2goserver 4.0.1.16 it is not possible to create new connections to the x2goserver. It must be connected to the modifications in the location of the session directories.
There was no server restart after the update (and can also not be executed), there were suspended and active sessions from the old x2goserver.
Any try to create a new connection ends up with the client status hang during "Starting" followed up by a time out error after a while.
The syslog is filled with messages like this:
Oct  2 08:28:12 ikkatrinsrv1 /usr/sbin/x2gocleansessions[12589]: neumann-77-1411537406_stRxfce4-terminal_dp32: state file for this session does not exists: /tmp/.x2go-neumann/C-neumann-77-1411537406_stRxfce4-terminal_dp32/state (this can be ignored during session startups)

The system is an Ubuntu 14.04.1 LTS on the most recent state. These other x2goserver related packages (x2goserver-extensions, x2goserver-fmbindings, x2goserver-printing, x2goserver-xsession) are also installed and at version 4.0.1.16. The remaining server configuration is complex using LDAP users and tmpreaper to regularly clean up tmp - but these directories are protected from clean-up '/tmp/.X11-unix /tmp/.x2go*'. It always worked with 4.0.1.15 and I truly liked the functionality of the x2go software.
