While not in your code, it is caused by it. From here, it appears as
though ParaView is loading your plugin and trying to access some server
manager XML content. That seems to be either not provided or is `NULL`.
ParaView could probably be more robust against it, but this still seems
like a plugin error.

Could you provide your `add_paraview_plugin` call for the plugin? It
appears as though `GetXMLs` should be generated, so if you could find
that in the build tree and provide it, that'd be useful as well.
