Hard to say why. Debugger is really your friend. If you haven't
already, I'd suggesting doing a debug build of ParaView and seeing
what's going on.

pqLoadStateReaction is the example of how to load a state. That's the
code ParaView uses when you click "Load State" from the File menu.

Just step through the code in pqLoadStateReaction.

pqLoadStateReaction::loadState() --> pqApplicationCore::loadState()
--> vtkSMSessionProxyManager::LoadXMLState() --> vtkSMStateLoader.
