[Paraview] Fwd: Is it a BUG with temporal filters or I am missing something? [Developers, could you please verify if this is a bug or not?]

Hi guys, I have asked this question few days ago. Has anyone seen the same
problem?

Hi,

This is what I am doing:
Load a time-aware PVD file like this:

<?xml version="1.0"?>
 <VTKFile type="Collection" version="0.1" byte_order="LittleEndian"
compressor="vtkZLibDataCompressor">
   <Collection>
    <DataSet timestep="0.0" group="" part="0" file="vel_vec_0.vtr"/>
    <DataSet timestep="0.2" group="" part="0" file="vel_vec_1.vtr"/>
    <DataSet timestep="0.4" group="" part="0" file="vel_vec_2.vtr"/>
    <DataSet timestep="0.6" group="" part="0" file="vel_vec_3.vtr"/>
    <DataSet timestep="0.8" group="" part="0" file="vel_vec_4.vtr"/>
    <DataSet timestep="1.0" group="" part="0" file="vel_vec_5.vtr"/>
    <DataSet timestep="1.2" group="" part="0" file="vel_vec_6.vtr"/>
    <DataSet timestep="1.4" group="" part="0" file="vel_vec_7.vtr"/>
    <DataSet timestep="1.6" group="" part="0" file="vel_vec_8.vtr"/>
    <DataSet timestep="1.8" group="" part="0" file="vel_vec_9.vtr"/>
    <DataSet timestep="2.0" group="" part="0" file="vel_vec_10.vtr"/>
  </Collection>
</VTKFile>

Apply any of the 'temporal filters' including
-Temporal Cache w/ Cache size = 2
-Temporal Interpolator w/ Discrete Time Step Interval = 0.1
-Temporal Shift Scale w/ [default values]

to the loaded dataset.
I just press the play button on the the animation toolbar and it either
gives me this error message or crashes.

  ERROR: In
/home/utkarsh/Kitware/superbuild/paraview/src/paraview/VTK/Filtering/vtkStreamingDemandDrivenPipeline.cxx,
line 934

vtkPVPostFilterExecutive (0x2d5d190): No maximum number of pieces has been
set in the information for output port 0 on algorithm
vtkPVPostFilter(0x2d26830).

I am using PV 3.14.0 (and .1) on both Ubuntu and Windows.

Has anyone experienced the same problem?
If the developers are reading this, could you please let me know if that is
a bug or not? I really need to decide soon wether or not to use PV for
post-processing of some particle-tracing part.

Thanks in advance,
Mohamad

****************************
A follow up on this problem.
if anyone is interested, I think it is a bug with the *rectilinear* vtk
reader (or any derivatives).
I converted the same dataset to *.vtu format, and read the file series. Did
the same experiment with temporal filters and everything looked perfectly
fine. No error message or crashing.
