Session resume not working

NX session resuming is not working with Ubuntu 8.04 Hardy 0.7.3+teambzr104-0freenxteam1~hardy1 and at least with MacOSX PPC nxclient v3.3.0-6 (haven't yet tried others). When creating NX session and then suspending it and creating NX session again - it won't resume previous session and instead creates new session. /etc/nx/node.conf is unchanged (besides logging settings) - as it comes with 0.7.3+teambzr104-0freenxteam1~hardy1 package installation. Nxserver log and nx session info from user .nx folder are attached to bug report. Its seems to be different from bug #268197 - as we don't use SU authentication and setting ENABLE_SLAVE_MODE="0" didn't help.
