[Paraview] pv freezes when merging blocks of angular periodic filter data

[Gena Bug]

Hi!

I was able to freeze Paraview by applying MergeBlocks filter to the data 
generated by AngularPeriodicFilter. In console I see a bunch of warnings:
{
Warning: In 
/home/kitware/dashboards/buildbot/paraview-debian6dash-linux-shared-release_opengl2_qt4_superbuild/build/paraview/src/paraview/VTK/Common/Core/vtkMappedDataArray.txx, 
line 47
20vtkPeriodicDataArrayIdE (0x6dce310): GetVoidPointer called. This is 
very expensive for vtkMappedDataArray subclasses, since the scalar array 
must be generated for each call. Consider using a 
vtkTypedDataArrayIterator instead.
}

Env: debian testing amd64, KF5, pv downloaded from the site.
