Some users in our lab are experiencing X11 crashes on their SL5.5/i386
workstation when they try to visualize with the driver OGLS. The driver
OGLI works though they report it to be less performant.

This is geant4 4.9.4.p01 and I can reproduce the problem with the
example A01 the following way :

  Geant4 version Name: geant4-09-04-patch-01    (18-February-2011)
                       Copyright : Geant4 Collaboration
                       Reference : NIM A 506 (2003), 250-303
                             WWW : http://cern.ch/geant4
Idle> /vis/open OGLSX
Idle> /vis/drawVolume   => CRASH or Segfault

I tried several workstations with different graphic hardware including
Intel and Nvidia and got the same result. I tried to disable the
graphics acceleration but it is no better.

=> Any similar experiences ? What can we do ?
