[Paraview] Problems loading plugins in pvpython

I'm trying to use the LoadPlugin simple module in pvpython, but I keep
getting this error:

>>> LoadPlugin("myLib.so", True)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File
"/usr/people/gagliard/Paraview/ParaView3.6.2-rc1/Utilities/VTKPythonWrapping
/paraview/simple.py", line 548, in LoadPlugin
    servermanager.LoadPlugin(filename, remote)
  File
"/usr/people/gagliard/Paraview/ParaView3.6.2-rc1/Utilities/VTKPythonWrapping
/paraview/servermanager.py", line 2115, in LoadPlugin
    LoadXML(f.read())
  File
"/usr/people/gagliard/Paraview/ParaView3.6.2-rc1/Utilities/VTKPythonWrapping
/paraview/servermanager.py", line 2084, in LoadXML
    if not parser.Parse(xmlstring):
TypeError: function takes exactly 2 arguments (1 given)

The help for LoadPlugin states:

Help on function LoadPlugin in module paraview.simple:

LoadPlugin(filename, remote=True, ns=None)
    Loads a ParaView plugin and updates this module with new constructors
    if any. The remote argument (default to True) is to specify whether
    the plugin will be loaded on client (remote=False) or on server
(remote=True).
    If you loaded the simple module with from paraview.simple import *,
    make sure to pass globals() as an argument:
    LoadPlugin("myplugin", False, globals()), to load on client;
    LoadPlugin("myplugin", True, globals()), to load on server;
    LoadPlugin("myplugin", ns=globals()), to load on server.
    Otherwise, the new functions will not appear in the global namespace.

So, I really should be able to pass it a single argument if I want to, but
whether I give it 1, 2 or 3 arguments it will still give me the same
TypeError. However, it works fine in the interactive Python shell. 

Is this a bug or have I forgotten to do something?

Cheers,

Adriano
