salome v6.4.0 universal binary fails to launch on Ubuntu 10.04.3 LTS

Hello,

the error I receive is

Traceback (most recent call last):
  File "/opt/salome/appli_V6_4_0/bin/salome/runSalome.py", line 684, in useSalome
    clt = startSalome(args, modules_list, modules_root_dir)
  File "/opt/salome/appli_V6_4_0/bin/salome/runSalome.py", line 629, in startSalome
    session=clt.waitNSPID("/Kernel/Session",mySessionServ.PID,SALOME.Session)
  File "/opt/salome/Salome-V6_4_0-LGPL-x86_64/modules/KERNEL_V6_4_0/bin/salome/orbmodule.py", line 170, in waitNSPID
    raise RuntimeError, "Process %d for %s not found" % (thePID,theName)
RuntimeError: Process 3172 for /Kernel/Session not found
Searching /Kernel/Session in Naming Service

I'll go back to v6.3.1...
