I checked the changes but they don't seem to cause the problem. r1.17 of
the file throws the same error and even core dumps.
I don't know if it's a vtk version related issue, cause it works fine on
the same image of the OS on machines with other hardware.
On Monday I'll try to run it on an older VTK version, just in case.
