[Paraview] Python View

[w.hunter]

when I try to start a "Python View" Layout in Paraview 4.1.0 I get the
following error:

*ERROR: In
/home/william/OpenFOAM/ThirdParty-2.3.x/ParaView-4.1.0/ParaViewCore/ClientServerCore/Rendering/vtkMatplotlibUtilities.cxx,
line 302*
*vtkMatplotlibUtilities (0x3aaab10): Could not call
'dpiCanvas.print_to_buffer()'*


*Traceback (most recent call last):*

line 302*
*vtkMatplotlibUtilities (0x3aaab10): Could not call
'pythonViewCanvas.print_to_buffer()'*

Using Scientific Linux 6.5 with python 2.6.6, numpy 1.4.1
and python-matplotlib 0.99.1.2 installed via yum. ParaView built using
makeParaView4 script provided for OpenFOAM-2.3.0, Qt 4.8.5 built from
source, compiler: Clang 3.3. The build was error free and everything else,
including python scripting, is working fine.

Any help much appreciated.
