[Mathieu Malaterre]

Michael,

	Thanks for report: this is fixed in CVS:

$ cvs ci -m"BUG: Call Build on the lookup table, also need to call 
Render explicitely before the ResetCamera to prevent segfault..." 
Medical3.cxx
/cvsroot/ParaView/ParaView/VTK/Examples/Medical/Cxx/Medical3.cxx,v  <-- 
  Medical3.cxx
new revision: 1.6; previous revision: 1.5
