[Paraview] Problem opening a pvd collection of pvtu files

[Pichler, Franz]

Hello everybody,
I have a problem opening a collection of pvtu/vtu files that I can open as a series (the *.00x.pvtu series).
I have a pvd file that looks like this
----
<VTKFile type="Collection" version="0.1" byte_order="LittleEndian"><Collection>
  <DataSet timestep="   1.000E-03" group="" part="0" file="Single_Simple_Cell/dickesmeshout0001.pvtu"/>
  <DataSet timestep="   2.500E-03" group="" part="0" file="Single_Simple_Cell/dickesmeshout0002.pvtu"/>
   ........
  </Collection></VTKFile>                              
-----
I also have the the pvtu and vtu file it relates to. I can open the vtu and pvtu files without problems. I can animate the frames when I open the pvtu series. I only need this pvd file to get the timesteps right.
The pvtu file looks like this:
-----
<VTKFile type="PUnstructuredGrid" version="0.1" byte_order="LittleEndian">
  <PUnstructuredGrid>
    <PPointData Scalars="dadada">
      <PDataArray type="Float64" Name="dadada" NumberOfComponents="1" format="appended"/>
	.........
    </PPointData>
      <PPoints>
        <DataArray type="Float64" NumberOfComponents="3" format="appended"/>
      </PPoints>
    <Piece Source="dickesmeshout0001par0016.vtu"/>
    <Piece Source="dickesmeshout0002par0016.vtu"/>
     .....
  </PUnstructuredGrid>
</VTKFile>

-----
The the vtu file looks like this:
----
<?xml version="1.0"?>
<VTKFile type="UnstructuredGrid" version="0.1" byte_order="LittleEndian">
  <UnstructuredGrid>
    <Piece NumberOfPoints="136" NumberOfCells="83">
      <PointData>
        <DataArray type="Float64" Name="dadada" NumberOfComponents="1" format="appended" offset="0"/>
			....
      </PointData>
      <CellData>
      </CellData>
      <Points>
        <DataArray type="Float64" NumberOfComponents="3" format="appended" offset="7644"/>
      </Points>
      <Cells>
        <DataArray type="Int32" Name="connectivity" format="appended" offset="10912"/>
        <DataArray type="Int32" Name="offsets" format="appended" offset="13236"/>
        <DataArray type="Int32" Name="types" format="appended" offset="13572"/>
      </Cells>
    </Piece>
  </UnstructuredGrid> <AppendedData encoding="raw"> .....
</AppendedData>
</VTKFile>

When I try to open the pvd file I get the following:
-----

ERROR: In C:\DBD\pvs-x32\paraview\src\paraview\VTK\IO\XML\vtkXMLReader.cxx, line 219 vtkXMLPUnstructuredGridReader (0A04BBE8): Error opening file C:\AVLKiste\Cluster/Single_Simple_Cell/dickesmeshout0001.pvtu

I have tried this with version 3.98.0-RC1-2-ge2fcf70 32bit on windows Itried the same on a linux machine version 3.14.1 64 bit And a windows version 3.14.0-rc2 and got similar error messages

NO idea if this is a bug but from what I understood this should work.
Any hint is appreciated
Thanks folks
