If one defines a simple xml with a Source containing a InputProperty named Input defined by a ProxyListDomain pointing to a Source using a DummyInput with link, it causes a segfault. This can be avoided by renamming the InputProperty to anything but "Input"

The segfault is caused by a recursive call to Producer->PostUpdate

For some reason the ProxyListDomain mixup input and outputs, resulting to this. (breakpoint in vtkSMProxyListDomain.cxx:93)

How to reproduce :

• Open ParaView
• Load test.xml as a plugin
• Create a "Test" source
• Apply

(seed_sources was named extended_source before 5.2, in case you test with earlier paraview version)
