Solved the problem by merely using paraview.simple.LoadState instead of 
paraview.servermanager.LoadState (as used in the examples: 
http://www.paraview.org/Wiki/ParaView/Python/Loading_and_saving_state):

https://github.com/romangrothausmann/ParaView_scripts/commit/9c897e34ebf338c709a37e61382e298f9603dc67

This makes me wonder when to use paraview.servermanager.LoadState?
Should the example 
(http://www.paraview.org/Wiki/ParaView/Python/Loading_and_saving_state) be 
changed to use paraview.simple.LoadState?

Still, I cannot get rid of this Warning. Any ideas?
