[Paraview] error in batch mode

[asterminator at freesurf.fr]

Hi,

paraview is really a great application !

but i found an error in batch mode i didn't understand. I read in
interactive mode an ensight file (there are some warnings during this
reading, i suppose they are due to second order elements i have in my
ensight files, the warning is :
# Error or warning: There was a VTK Warning in file:
/home/kitware/ParaViewReleaseRoot/paraview-1.2.1/VTK/IO/vtkEnSightGoldReader.cxx(1540)
 Only vertex nodes of this element will be read.
)
then i save the batch file toto.pvb (File/Save Batch Script) and i exit.
Finally i launch paraview in batch mode : > paraview -b toto.pvb. The error
appears :
Errors while exiting ParaView:
ERROR: In
/home/kitware/ParaViewReleaseRoot/paraview-1.2.1/ParaView/Filters/vtkPVEnSightMasterServerReader.cxx,line 177
vtkPVEnSightMasterServerReader (0xa25a420): ExecuteInformation requires a
Controller.

Where am i wrong ?

Thx
