engine segv's with -dump

[biagas]

Describe the bug

I was looking into regression failures on my vtk 94 branch and decided to use -dump to compare pipeline results of current visit with vtk94-visit.

One case causes the engine to segv, here's that script (taken from pick.py)

OpenDatabase("sid97.silo")
AddPlot("Boundary", "mat1")
AddOperator("Slice")
slice = SliceAttributes()
slice.originType = slice.Point
slice.originPoint = (7400, -1300, 1000)
slice.normal  = (0, 1, 0)
slice.project2d = 1
SetOperatorOptions(slice)

DrawPlots()
ResetView()
SetViewExtentsType("actual")
SaveWindow()

Other scripts I created do not cause the segv.
