[Paraview] Error trying to run python script

[Utkarsh Ayachit]

Chuks,

The trace missing the filename is indeed a bug. We are working on
refactoring the tracing code right now, so tracing should get better
in the next release.

The error you get when you explicitly set the FileName is due to the
fact that the property is called FileNames and not FileName
(http://www.paraview.org/ParaView3/Doc/Nightly/www/py-doc/paraview.simple.XDMFReader.html?highlight=xdmfreader#paraview.simple.XDMFReader).

To overcome such issues, you can also use the OpenDataFile()
(http://www.paraview.org/ParaView3/Doc/Nightly/www/py-doc/paraview.simple.html#paraview.simple.OpenDataFile)
function instead:

reader = OpenDataFile("....foo.xmf")
