If python.exe crashes -- ie exits completely without a traceback, then
it's most likely a flaw in the extension module which is capturing the
image. If that's the case, there's nothing you can do in Python code to
prevent it; you need to work with the project maintainers to fix that.
If you're getting a traceback but the console window is then closing too
fast for you to see it, then try running the code from an open console
window rather than double-clicking on it. (You don't say how you're
kicking the code off so I'm offering this just in case)
