pypython/pvbatch vtkMatplotlibMathTextUtilities parse failure
When running pvbatch/pvpython on e.g.
SaveAnimation('animation_frames/frame.png', layout1, ImageResolution=[1920, 1080], FrameWindow=[0, 300])
failure occurs when parsing e.g.
$\epsilon_{rsp}=80.1$
giving the error
( 118.609s) [paraview]vtkMatplotlibMathTextUt:616 WARN| vtkMatplotlibMathTextUtilities (0x7ffa4e0666e0): Failed to compute rows and cols for cell : $\epsilon_{rsp}=80.1$
FWIW I get this error when instantiating pvpython/pvbatch:
Could not find platform dependent libraries <exec_prefix>
but it's presumably unrelated.
