Thanks for you reply Ken.

Sure. Please download this sample dataset from
http://miyav.ath.cx/t_/imagedata.tgz (54KB). The package includes 3
binary vti files, 1 legacy ascii vtk file, a time series pvd file and
2 text files of stack dump after crash. The image data consists of
several 10^3 point data scalars.

There are multiple ways to replicate the problem:

Case1 - Open file iter0.vti; add Gradient Magnitude filter; Apply {pv
shouldn't crash yet, but there is no meaningful output}; Delete
Gradient Mag. filter; Delete iter0.vti {pv crashes with stack dump in
error1.txt}

Case2 - Open file steps.pvd; Play time steps; Add Gradient Filter;
Apply {pv crashes with stack dump in error2.txt}

Case3 - I can not replicate this consistently. But, with Case1 after
Apply step, I sometimes get

ERROR: In /home/levent/pkg/ParaView3.2.1/VTK/Imaging/vtkImageGradientMagnitude.cxx,
line 255
vtkImageGradientMagnitude (0x1afff70): Execute: input data type, 11,
must match out ScalarType 10

on the output window. Following this is identical to Case1.

In Windows version, Case1 hangs paraview (busy wait), Case2 crashes
with Qt error in my previous post. No stack dumps.
