Comment 1 Ivana Hrivnacova 2012-11-14 16:32:41 CET 
The field04 example calls vis.mac before run/initialize, what causes a message:
ERROR: G4VisCommandSceneAddVolume::SetNewValue:
  No world.  Maybe the geometry has not yet been defined.
  Try "/run/initialize"
from
/vis/drawVolume

However when vis.mac is reduced to 
/vis/open OGL 600x600-0+0
/vis/viewer/set/viewpointVector 1 1.5 1.1
/vis/viewer/set/viewpointThetaPhi 110 140
/vis/viewer/zoom 1.4
as no further setting has a good meaning, then the program (built with Qt) crashes with gdb back trace:
./field04
