Many thanks for your reply. No, and I'm still stuck. I tried Your suggestion to 
remove [0] 
(https://github.com/romangrothausmann/ParaView_scripts/commit/e40d1016d698ee363500bb9bf04f29add89b99dd), 
which changed the reported error from:

   File 
"/opt/paraview-5.3.0_GL1/lib/paraview-5.3/site-packages/paraview/servermanager.py", 
line 375, in SetPropertyWithName
     prop.SetData(arg)
   File 
"/opt/paraview-5.3.0_GL1/lib/paraview-5.3/site-packages/paraview/servermanager.py", 
line 803, in SetData
     raise RuntimeError("This property requires %d values." % 
self.GetNumberOfElements())
RuntimeError: This property requires 3 values.

to:

   File 
"/opt/paraview-5.3.0_GL1/lib/paraview-5.3/site-packages/paraview/servermanager.py", 
line 375, in SetPropertyWithName
     prop.SetData(arg)
   File 
"/opt/paraview-5.3.0_GL1/lib/paraview-5.3/site-packages/paraview/servermanager.py", 
line 1296, in SetData
     self.SMProperty.AddProxy(value_proxy)
TypeError: AddProxy argument 1: method requires a VTK object

Any ideas on this?
Would You say it is a general problem in the py-code or could it be caused by 
the content of the PVSMs I'm trying to combine?

Many thanks for looking into this.
Roman
