Closing a script saved in the tlpx without saving it crashes Tulip

[renoust]

This one I can reproduce easily on my setting with the attached tlpx file (remove .zip):
paintingsvis.tlpx.zip

Try quit the third script from the python view, this one is not saved on disk (other scripts are saved on disk here).
While quitting this script and saying no to saving it, I get the systematic crash (here is the stack trace)
