Managing errors generated by third party software (VTK) called via PyCall

General Usage

I am trying to properly manage the exceptions created by an external software, VTK. I am calling some of its functions from PyCall as in the following example.

using PyCall
@pyimport vtk as vtk
reader = vtk.vtkXMLUnstructuredGridReader()
reader[:SetFileName]("test") #Doesn't exist
try
     reader[:Update]()
catch
     println("Error")
end

But the following window shows up instead and crashes Julia. Any idea what I am doing wrong?
